Most lett véglegesen elegem a kanadai mentalitásból. Történt, hogy megkérdeztem az embert, akitől béreljük a lakást, hogy van e valami ötlete, hogy hová költözzünk, ami nem ilyen nagyváros mint ez, mert nem akarok túl nagy lakáshitelt felvenni, freelancerként meg úgyis tudok bárhonnan dolgozni, de azért legyen normális hely normális iskolával a gyereknek. Nem elég, hogy felsorolt négy-öt alternatívát, hanem holnap este még el is visz a legtávolabbiba (120 km oda, 120 vissza), hogy tudjak valami képet alkotni róla. Mi bajuk van ezeknek az embereknek?
** Synopsis: By analyzing the gas motion of an extraordinarily fast-moving cosmic cloud in a corner of the Milky Way, astronomers found hints of a wandering black hole hidden in the cloud. This result marks the beginning of the search for quiet black holes; millions of such objects are expected to be floating in the Milky Way although only dozens have been found to date. **
It is difficult to find black holes, because they are completely black. In some cases black holes cause effects which can be seen. For example if a black hole has a companion star, gas streaming into the black hole piles up around it and forms a disk. The disk heats up due to the enormous gravitational pull by the black hole and emits intense radiation. But if a black hole is floating alone in space, no emissions would be observable coming from it.
A research team led by Masaya Yamada, a graduate student at Keio University, Japan, and Tomoharu Oka, a professor at Keio University, used the ASTE Telescope in Chile and the 45-meter Radio Telescope at Nobeyama Radio Observatory, both operated by the National Astronomical Observatory of Japan, to observe molecular clouds around the supernova remnant W44, located 10,000 light-years away from us. Their primary goal was to examine how much energy was transferred from the supernova explosion to the surrounding molecular gas, but they happened to find signs of a hidden black hole at the edge of W44.
During the survey, the team found a compact molecular cloud with enigmatic motion. This cloud, named the “Bullet,” has a speed of more than 100 km/s, which exceeds the speed of sound in interstellar space by more than two orders of magnitude. In addition, this cloud, with the size of two light-years, moves backward against the rotation of the Milky Way Galaxy.
To investigate the origin of the Bullet, the team performed intensive observations of the gas cloud with ASTE and the Nobeyama 45-m Radio Telescope. The data indicate that the Bullet seems to jump out from the edge of the W44 supernova remnant with immense kinetic energy. “Most of the Bullet has an expanding motion with a speed of 50 km/s, but the tip of the Bullet has a speed of 120 km/s,” said Yamada. “Its kinetic energy is a few tens of times larger than that injected by the W44 supernova. It seems impossible to generate such an energetic cloud under ordinary environments.”
The team proposed two scenarios for the formation of the Bullet. In both cases, a dark and compact gravity source, possibly a black hole, has an important role. One scenario is the “explosion model” in which an expanding gas shell of the supernova remnant passes by a static black hole. The black hole pulls the gas very close to it, giving rise to an explosion, which accelerates the gas toward us after the gas shell has passed the black hole. In this case, the astronomers estimated that the mass of the black hole would be 3.5 times the solar mass or larger. The other scenario is the “irruption model” in which a high speed black hole storms through a dense gas and the gas is dragged along by the strong gravity of the black hole to form a gas stream. In this case, researchers estimated the mass of the black hole would be 36 times the solar mass or larger. With the present dataset, it is difficult for the team to distinguish which scenario is more likely.
Theoretical studies have predicted that 100 million to 1 billion black holes should exist in the Milky Way, although only 60 or so have been identified through observations to date. “We found a new way of discovering stray black holes,” said Oka. The team expects to disentangle the two possible scenarios and find more solid evidence for a black hole in the Bullet with higher resolution observations using a radio interferometer, such as the Atacama Large Millimeter/submillimeter Array (ALMA).
1 to 4) AMX-30 “Pluton” Launch Vehicle. French nuclear-armed short-range ballistic missile system launched from a transporter erector launcher platform mounted on an AMX-30 tank chassis. It was designed to provide the tactical part of French nuclear deterrence during the Cold War. The Pluton came in replacement of the U.S.-built “Honest John” missile. It had an operating range between 17 and 120 km, with a error probability of 150 m. The warhead had a yield of 25 kilotons.
5 to 7) AMX Leclerc. French made main battle tank system for French and UAE armed forces. Compared to other main battle tanks of Western origin, the Leclerc took to some rather alternative design directions. It’s one of the lightest modern main battle tanks in service at 54,500 kilograms and is fitted with an autoloader. The autoloader is more commonplace in Soviet tank designs which allows a smaller overall profile while reducing the required crew. As such, only three crew are required to run the Leclerc
8 to 10) Merkava Mk I. Israeli MBT. The tank began development in 1973 and entered official service in 1978. Four main variants of the tank have been deployed. It was first used extensively in the 1982 Lebanon War. The Merkava features several novel features and prioritized crew protection above all else. The engine is positioned in the front unlike almost every other MBT in the world and gives a extra protection to the crew. The rear of the tank has clamshell folding doors that allows a maximum of six infantry to be carried in the tank.
panzerfluch, sorry for posting it so late!
71 km: You value efficiency more than anything. You have played KSP since the earliest versions (and were annoyed when the atmosphere limit was raised from 34.5 km to 69 km, and then again to 70 km) and have done really complex missions, and to do a Grand Tour of everything in the Kerbol system is your ultimate aspiration (or maybe you’ve already done it?). You also probably achieved the given orbit with an SSTO and MechJeb.
80 km: While you’re trying for efficiency, your reasons for picking this number are very similar to those of 100 km.
100 km: You like 100 km, as it is a nice round number. You also like that in KSP, all the planet radii are given in exact numbers in kilometers (such as Kerbin’s being 600 km). More likely than not, when you perform a gravity turn, you also turn exactly 45 degrees at 10 km, and were outraged when the atmospheric changes made this sort of gravity turn inefficient.
121 km: The 50x time warp limitation at 120 km annoys you.
601 km:Any sort of time warp limitation annoys you.
2,863 km (KEO): You’re playing KSP heavily modded, including but not limited to TAC Life Support, FAR, RemoteTech, Kerbal Construction Time and a couple of visual mods. God, can’t Squad just make these mods stock already?
Elliptical 71 km x 251 km: You’re playing science/career mode and are really just looking forward to mining all the science from Kerbin right now.
Any other elliptical orbit (including “orbits” with periapsis below 70 km): You’re still a beginner in KSP, still confused by the multitude of concepts you have to wrap your head around.
You haven’t reached Kerbin orbit yet: Either you’re completely new to KSP, or you gave up trying to reach orbit early on and are now focusing on projects that do not have to do anything with space (e.g. submarines, airplanes, ground-based vehicles). Eventually, KSP will stop meaning “Kerbal Space Program”, right?

This is a story of vengeance. It goes way back to the genesis of vampires, it’s the story of how the angel Michaela fell from heaven into the unsightly earth.
Szerintetek pancsolás(gyanús) benzin jelentősen növeli a kocsi fogyasztását?
Egy, egyetlen nagy hálózathoz sem tartozó benzinkúton (sőt, még egyetlen magányos kútjukat sem láttam korábban, lehet h cs az az egy kútja van az üzemeltetőnek) vagy 3 forinttal olcsóbb volt a 95-ös benya még a standardan alacsony lukoilos áraknál is. Törzsolvasóim sejthetik, hogy nem tudtam ellenállni fillérbaszásos ösztönvilágomnak. Közel üres tankkal érkeztem, telivel távoztam. Majd fogyasztott a vas, mint Timike Andy bátya platinahitelkártyájával.
Közel 9 literes átlagfogyasztás legújabb szerelmemen, a matricamentes 51-es úton, ahol 6 alatt amúgy jellemzően, hisz kevés a a lakott település, a nyílt szakaszokon meg az ideális 90-100 Km/h tempó jáccik.
Budapesti, meg egyéb lakott területi szakaszokon pedig mint valami többszáz lovas, ötliteres motros, amerikai országúti cirkáló az ötvenes évekből: 17, meg18 litert mért a kompi.
Már gondoltam, hogy fasszer, megint beszart a lambdaszonda, akkor jártam úgy (a kocsi számítógépe állandóan motorhibaüzenetet jelez, de mindkét szonda cserélve, a vezetékek átnézve, csak a komputerét javítani, vagy cserélni már nem érné meg).
Majd újratankoltam és látványosan helyreállt a fogyasztás is. Másnap levittem az egyik lányomat Szabadkáról a belgrádi reptérre. Szerb autópályán ugyan 130 helyett csak 120 Km/h a megengedett, amit tartottam is és így némiképp ugye kedvezőbb a fogyasztás, no de hát akkor sem számítottam ennyire klaszára: 6.3 literre/100 Km. És a kompjuter nem szarhatott be, hisz a benzinóra alapján is ez a realitás.
Amennyire én tudom, Magyarországon az OMV kivételével a nagy hálózatok (pl a Schell, stb is) a MOL-tól veszi nagykerben mind a benyát mind a dízelt, max a saját adalékaikat adják hozzá.
Egy nagy hálózatnak nyilván picsaszigorú a belső policyje, hogy a franchise-osaik ne rontsák a jóhírüket, de hát azért hallani olykor bepróbálkozásokról.
Tök hüye vagyok ehhez (is) de kb a jó öreg vizes trükköt tudom elképzelni, amit a kis, független kutacskások esetleg eljátszanak. Mondjuk ezer literenként felütni egy liter vízzel a benyát meg a nyálat. Sok kicsi talált pár száz forintocska körüli tétel sokra megy azért éves szinten.
Mint ahogy kissé durvábban szokták felvizezni az élőhúsban eladott vágóbikákat. Egy 600 kilós bikának, ha jól benyalatják sóval, majd ledugnak a a jószág torkán egy gumislagot, akár 100 liter vizet is bele lehet tolni. (Mondjuk szét is lehet így durrantani egy bikát, hogy belepusztuljon, ilyesmi is előfordul.) Ennek az ellenszere, ha a vevő paraszt azt mondja az eladónak, hogy a falu másik végén van a mázsája, mondjuk a haver silójánál, hozzáköti a bikát a traktor utánfutójához és szépen-lassan megfuttatja, hogy kiizzadja a jószág a hús áron eladni próbált vizet.
De persze lehet, hogy a benzinnel nincs is ilyen vizes trükk, meg semmi más. Pláne, lehet h az a kút mégis vétlen, ezért priviben se kérdezzétek, hogy melyik volt. Hiányzik egy jó kis hitelrontásos ügy, mint fuldoklónak a 444-es törzskommentelői életmódtanács:D
De a tumbli Walter Wight-jai ne fogják vissza az emeltszintű kémiaérettségi nagybetűs élettel keresztezett okosságaikat. Várom az ötletbörzézést.
Ho scattato questa foto mentre ero in viaggio per tornare nel mio piccolo ma accogliente monolocale universitario.
Ho imparato che viaggiare comporta una partenza. E una partenza richiede coraggio, coraggio e un altro mucchio di cose molto confuse che proverò a spiegare. Partire significa frapporre una distanza fra te e tutto ciò che hai di più caro, famiglia, amici, amore, ricordi, i tuoi posti sicuri; chilometro dopo chilometro comprendi che si stanno allontanando, te ne stai in qualche modo temporaneamente separando.
Tre anni fa ho rischiato. Sono saltata su un treno carica di paure, speranze e qualche lacrima, ho osservato le porte chiudersi lentamente (o forse fin troppo velocemente) dinanzi agli occhi di qualcuno che amavo, proprio come i film, sapete? Ed è stato persino straziante, come nei film.
Ho vissuto il mio primo anno da fuori sede con un perenne magone allo stomaco e un senso forte di disagio, come se fossi nel posto sbagliato, ho trascorso il primo anno tornando spesso a casa e stringendo continuamente i denti.
Ti senti sola, ecco. Ti senti disorientata, ancora troppo attaccata alla tua vera casa, la tua vecchia vita. Non la accetti, quella distanza, tutte le possibilità che ti ritrovi ma che non sai come gestire, le persone nuove e strane che non sai come avvicinare, non sai se poterti fidare.
Inciampando ogni tanto passa comunque il tempo. E allora capita qualcosa di molto strano. Tutto ad un tratto stai bene. Magari sei andata a fare la spesa e chissà come ti sei ritrovata a bere un bicchiere di vino da sola, semplicemente perché ti andava. Magari il signore gentile del bar di fronte casa tua ormai ti sorride sempre e ti chiama anche per nome. Magari ti trovi a passeggiare per delle strade che d'un tratto sembrano farti compagnia, ne hai bisogno quasi, di quelle strade, quelle camminate. E che importa se sei sola?
Ci tenevo a dire a tutti gli studenti indecisi che ne vale la pena, si. Avere una propria casa e prendersene cura, fare il bucato, cucinare, incontrare delle persone che ti fanno stare bene, e anche quelle che sanno ferire. Quelle che semplicemente non sono fatte per starti accanto. Vale la pena caricarsi di qualche responsabilità in più e diventare un po’ più grande, poco alla volta. E uscire, ritrovarsi improvvisamente in un gruppo, una seconda casa, una famiglia, da un momento all'altro. Tornare dall'università e bussare ad una porta. Studiare, sentirsi soffocare per poi respirare in quegli attimi di tenerezza e sorrisi. E le partite a carte lunghissime mentre fuori piove, e la musica, le chiacchierate, fare i matti e sentirsi scemi, ma scemi insieme. E prendere la macchina e andare, sempre con quel misto di paura e prudenza addosso quanto basta, ma andare. Percorrere quei 120 km che diventano magicamente casa.
Rischiate. Vivete. Abbiate coraggio sempre, anche quando fa paura, anche quando tutto va male.
Saranno bei ricordi.
Saranno una parte della vostra esistenza, per sempre.
“Where’s the puppy, mommy?” You tug on your mother’s dress, but she dismisses you. Feeling guilty, she turns back and ruffles your hair. “Sorry sweetie but looks like it ran away.”
And for the luxurious life you follow - this was the first memory of disappointment. But it was only a matter time before everything in your life would abandon you…after all, who could stand you?
Sweet nothings stumble from your lips and honey words entrench in the air. This is your life. You whisper enticing words into old men’s ears and it proves no difficulty for you - you’ve done it countless times over.
You’re all gussied up, dressed like a doll to perfection. Women envy you as you walk past and men become flustered. “God that guy was disgusting.” You whisper out of the corner of your mouth to Secretary Yoona.
She smiles half-heartedly. “I’m sorry miss.” You sigh internally. Your father couldn’t accompany you this evening but you don’t mind. It’s easier when he’s not here; he won’t be able to sense your fatigue that you’ve been masking with easy smiles.
You grab a glass of golden champagne to help you ease up, weaving through the crowd to make your way to chief executive blah blah blah blah of your father’s rival company. Here we go again, you think. As you prepare an alluring smile, you feel a ripple through the air.
Bang. The Corporate Chairman of Swallow Enterprise falls to the ground.

earlier with the promise that practice wouldn’t last as long as usual
today so he wanted to spend time you. Since you didn’t have anything
planned for the evening – and was it even possible to say no to
your boyfriend? - you agreed to meet at the park and get something to

wasn’t usually something that worried Kuroo. He knew you were busy
with practice and school as much as he was and it wasn’t unusual for
both of you to be a bit late.
worried him was the fact that you didn’t respond to his texts or his
calls. You lived about twenty minutes away so it shouldn’t take you
when Kuroo was about to stand up and go look for you, insecurities
and worries buzzing in his head like a swarm of wild hornets, a voice
he would recognize anywhere yelled out a panicked “STOP!” before
something collided with the back of his legs.

sending him straight to the dewy grass below. Looking back he was
suddenly smothered with something white and fluffy and for a second
he thought a stray cloud had attacked him.

cotton candy with a foxy face and round, dark eyes that stared up at
him like the tiny poof expected a treat for the stunt he just pulled.

attached to it, you immediately grabbed the dog but the little thing
had other ideas, jumping away from you and up onto the bench Kuroo
was sitting on just seconds ago.

but I didn’t know what to do with this little guy here and he freed
himself from his collar about ten minutes ago and I’ve been running
ever since and-”
woah!” Kuroo chuckled deeply and held up a hand. He smiled gently
at you, patting the dog with one hand. “No worries. You’re safe and
sound and here, I mean it would’ve been nice of you to answer your
phone but hey life isn’t always a bowl of cherries.” He leaned
forward and placed a tender kiss on your lips, ignoring the teeth
that were gnawing at his hand.
sorry”, you repeated, once you separated. “I forgot it at home.”

down next to your dog, he grabbed the collar from you. Fastening it
was a bit harder with the little thing trying to escape, happily
yipping and yapping because he thought Kuroo was trying to play with
him. “So who’s this little ball of wool?”

smile and doe eyes.
Kuroo chuckled. “I didn’t expect to become a father so soon”, he
said. “But with this little renegade I guess I can manage.”

that was not was Oikawa had hoped to be the first words out of your
mouth when you opened the door. But he was more hurt by the tone your
voice had. Like he came at a very bad time.
a hand over his heart he acted deeply hurt, sighing and giving you
the best pout he could muster. “I’m wounded!”, he exclaimed.
“Here I am trying to light up your afternoon and this is is how you
greet me.” He shook his head. “I’m truly hurt, ____-chan.”
rolled your eyes, still keeping the door mostly closed. Right now
only your face and a little part of your upper body could be seen.
“Well life is a bitch, isn’t it?” If he wanted to be a drama
queen he had to be prepared for the sass that was to come. “This is
a really bad time anyway.”
He tried to look around you but you successfully blocked his view.
“Do you have guests over? Are you ashamed of me, ____-chan?”

crashing into Oikawa either.

rolling your eyes, motioning for both of your boys to enter.

following your boyfriend as happily as he greeted him, yipping and
jumping around like a bouncy ball.

ground where he was playing with the puppy. “Why didn’t you name
him after me? That would’ve been adorable.”
snorted and went to get both of you something to drink. “I don’t
need two of you running around. One is hard enough to manage.”
twelve missed calls and about eighty messages from you was alarming
enough for Bokuto. Not knowing whether the urgency in your ‘get your
ass over here NOW!!’ and the ‘fucking HURRY KOU!!!’s was because of
excitement or anxiety became the cherry on top.

tight around his legs,
ignoring the others who waved him goodbye and immediately sprinting
towards your house, which was, fortunately close to school.

wasn’t all his attention focused on seeing you unharmed
and safe, he would’ve
been glad to have worn his kneepads. Already expecting the worst when
you didn’t immediately answer, his anxiety grew and a plan was
forming in his head, wondering if you would be very mad if he smashed
your window and climbed in and-
the door finally opened he didn’t even get a second to enjoy the
relief flooding his body because you grabbed his arm and pulled him
through the door with accusations spilling from your brightly smiling
lips. He was momentarily blinded by the feelings your obvious
happiness caused in him and started smiling without noticing.
then you two arrived in the living room and he realized why you had
wanted him to come over so badly.

your mother ever found out about that.

with each other from the get go.
explained that you had finally convinced your parents to get a dog
and had went with them to the animal shelter after school. The rest
was a story of love at first sight because the little dog may or may
not have reminded you of your boyfriend with his endless bouncing and
excited barking and the tail that was wagging 120 km/h.
hindsight you probably should have reconsidered getting another
companion that had more energy than everyone you knew combined.
However, seeing both of them playfully fighting over the ball on the
floor, not being sure which one made you more happy, definitely
washed away the doubts and had you joining them.
Würzburg is located in the region of Franken (Franconia) in Bayern (Bavaria), Southern Germany. Situated on the Main river, it lies at about equal distance (120 km) between Frankfurt/Main and Nürnberg. Population ~ 125,000. Founded in the 10th century, it served as the home of powerful prince-bishops for centuries. It’s renowned for the Residence, regarded as one of the finest palaces in Europe and a high point of Baroque art (a UNESCO world heritage site). Würzburg is also home to one of the oldest churches in Germany, built in the 8th century on top of a former pagan shrine. The city was the center of the kingdom known as Franconia. In the 19th century, Napoleon merged Franconia with Bavaria, by which the city is ruled to this day. Würzburg experienced heavy demolition during a 20-minute bombing raid in 1945 which destroyed 80% of its buildings. The city has since been rebuilt, though not as painstakingly true to its original architecture as other historic towns. Anyone eager to visit this town to study its historic architectural structures should be prepared to see its restored buildings placed next to post-war modernistic houses.
Nach einer Fahrt durch wunderschöne Landschaft sind wir in Santa Isabel angekommen, ca 120 km bis zum Pazifik.
Hier trennen sich unsere Wege.
Nach einem Monat ist uns klar, daß es nicht mehr Gemeinsam weitergehen kann. Wir sind einfach zu verschieden und die Konflikte haben zunehmend die Reise überschattet. Keine Schuld, keine Vorwürfe und keine Kompromisse mehr.
Wir werden uns in La Paz wiedersehen und verabschieden uns freundschaftlich.
Buen viaje Max.
Ein neues Kapitel beginnt.
Ich bleibe in dem herrlichen Ort Santa Isabel, Max folgt der Panamericana.
Ein steiler Anstieg führt in den Ort, wo ich ein sehr schönes und freundliches Zimmer finde, in dem ich auch noch am nächsten Tag bleiben werde. Es gibt einiges neu zu ordnen und zu planen.
How fast do you think Toothless is at his top speed? How long do you think he'd be able to maintain that speed (eg several minutes, a few hours, all day)?
Excitingly enough, we actually have a canon answer to this! “The Art of How to Train Your Dragon” on p. 146 says that there are times Toothless exceeds one hundred miles per hour. When Toothless is diving, he probably hits one hundred twenty miles per hour, which is about the terminal velocity of a human falling (in the Wiki article they say it’s one hundred fifty but I don’t think that’s quite right?).
Chris Sanders, in the How to Train Your Dragon filmmaker’s commentary, remarks during the moment Toothless divebombs the Red Death:
One of the things we really wanted to get out of this thing is the idea that flying on a dragon like this wasn’t easy and it wasn’t gentle. That when you hit these velocities, that things became actually very shaky and rough and that it was a real physical activity to actually fly on the back of Toothless. And that diving shot was the shot where we were trying to get that across.
The likelihood is that Toothless does not fly this fast when he is going straight horizontally. I imagine that the 120 mph (160 km/hr) speeds are only when Toothless is diving, and that his top horizontal speed is much slower. I tried to do some quick bird research and found that birds which can dive at speeds higher than 100 mph typically fly about half that rate horizontally for their top speed. This means that Toothless’ maximum horizontal speed is probably about 50-60 miles per hour (80-95 km/hr). His average horizontal speed I imagine is around 40 mph given what I have seen from birds somewhat of his wing shape and speeds.
Regarding how long Toothless can maintain his top 60 mph speed, I do not know. Probably not that long; I would say minutes over hour at an intuition, anyway. I found a lot of research about how long birds can sustain their average speed of flight, but not top speed. But I did find some information that might clue us in to take a guess about this.
For instance, hovering expends about double the energy of flying average speed, and that flying top speed does not expend nearly the same amount of energy as hovering, which is putting birds at their absolute physical limits. The dragons in How to Train Your Dragon can hover (despite the fact that, realistically speaking, they anatomically would not be able to do so, and the creators have even acknowledged that). We see Toothless hover in How to Train Your Dragon 2, and he sustains it for a significant period of time all things considering. I am pretty sure he hovers for five minutes during the final “Toothless Found” scene. This means he could fly at top speed even longer than that. This means he could go for a while, but it’s probably going to be more of ten or twenty minutes rather than an hour.
Also, the size and shape of wings does affect how fast and how far a bird can travel. By looking at Toothless’ wing shape, we can take a better guess about whether or not he’s built for flying fast, and consequently about how well his body does handling top speeds.
So here are Toothless’ wings:
And now here are some of the basic bird wing shapes:
Toothless’ wings probably look most like A or D from the diagram. Note that this is me just looking at these wings, trying to read up on wing ratios, and making a very, very non-educated guess.
Now the example of a bird with wing type A, that is, elliptical wings, includes the flycatcher and most songbirds, and it looks sort of like this:
I think these wings look somewhat close in shape to Toothless’. Of course the feathers are going to have notably different properties than Toothless’ leathery wings, but the unique features for this type of wings are quick turns for forested environments and quick takeoff. Toothless does appear to be a quick turner and he can do takeoff from a standstill.
Now wing type D is what we see in eagles and vultures. These guys’ wings allow them to carry heavy loads and to lift up high at slower speeds. I don’t know what to make of that, given that Riders of Berk makes it clear Toothless is the fastest of all the dragons around Berk, at least.
I’m not going to pretend to be an avian expert, so I’ll stop right there. But based upon what we know of these wing types, they do not seem to be wings built for endurance as much as for other features. He can fly extremely fast, but most creatures that run or fly fast are built for short bursts rather than long journeys. Just think of how quickly a cheetah wears out after going 70 mph. This means I doubt that Toothless could maintain his top speed for an hour. He’s going to go his fastest for only minutes at a time. But then I am no expert whatsoever, and I could be stating utter nonsense at this point.
If there is an ornithologist anywhere around here (or heck someone who knows bats! Bats would be great since they’re mammals and Toothless was designed to look mammalian!), I’d love to hear what your thoughts on the matter are! Please correct me with all the mistakes I probably made.
But to wrap up: Toothless flies fast. He probably flies at 40 mph on average, goes up to 60 mph at his top speed horizontally, and can dive over 120 mph. I would imagine that the top speed would tire Toothless incredibly quickly and he would only be able to do it for a few minutes. But then given how strong we see Toothless is, what with his ability to hover and clearly fly at his normal speed for a while, maybe he can do top speed longer than that.
