I witnessed history today. Eastern Airlines was one checkride from getting their new Part 121 Carrier Certificate when I took these photos. About half an hour later the bird, a 737-800 officially titled “Spirit of Captain Eddie Rickenbacker”, lifted into the Tallahassee skies and the company is on its way to resurrection and new life. I felt like I was looking at a beautiful piece of lost history, and I’m still not completely sure I really saw it.
