Wow, from their pictures you can see that USAirways gave up on their MetroJet service from all the parked red 737-200’s.
I remember reading an article about desert storage soon after 9/11 as airlines from around the world work flying in aircraft to park. They seal up the aircraft skin, cover the windows, remove all the fluids and put it out to storage. They quoted a turn around time that I can’t remember. It was something like 3 weeks between when an airline called saying they wanted to reclaim their aircraft to when the staff could get it back to flying condition. They parked 2 of our 3 turboprop fleets in the desert after 9/11. I know a few pilots who got to make delivery flights to Roswell. They said it was just awesome to see all the aircraft parked.
