The Smoke Angels.
How does an aircraft fly?
Think of it like this, due to the design of the wing, larger number of
air molecules are hitting the bottom portion of the aircraft than the
As a result, a upward force acts on the wing, hence the wing lifts!
This works fine till we get to the wing tips.
the wingtip, the air from a higher pressure wants to move to the region
of lower pressure. And as a result, this forms vortices ( fancy name
for the swirling motion of air ) known as Wingtip Vortex. ( because its
formed in the wing tips!!! )
And it is due to the ramification of this, that we obtain those gorgeous smoke angels. Pretty cool huh ?
Have a great day !
