She is a very sick woman. And why was she wearing a heavy winter coat several days ago?
LOL, I should keep my yap shut and leave the speculation on this to people who know how civilian craft operate...
I tend to see it from the perspective that all the work goes into the airworthiness after the plane lands and the crew hand in their gripe sheets which are all worked until the plane is ready again for flight, everything is topped off, and it is just waiting for a pilot to jump in because it is ready to go.
I can understand how a 737 would take longer to preflight than a fighter.
