Also if the overwing door is open and flames start closing in you can
reclose the door, not too easy if you've chucked it outside.

I noticed over the past few years that this has changed: they tell you to "place the door on the seat beside you before exiting the plane". This never made sense to me: having a big bulky door blocking the exit. Makes more sense to toss it out. Nevertheless, the switch from "toss it out" to "place it on the seat beside you" was something I thought only I noticed but never gave it much thought.

I have found that the pilots are always very squeemish about the doors, which, 15 years ago, a pilot told me cost $8,000; $16,000 for ones that slide open on rails. At the time, we teased the poor bugger about it and suggested that we move off the gold standard and adopt the "helicopter door standard". For the rest of our field trip, we quoted all expenses in terms of helicopter doors. I'm sure the pilot was fed up with our irreverence by the end of the 8-day trip.

It'll push him right over the edge. It may cost about 10 helicopter doors for the therapy sessions required to restore his mental state. I don't know how many Boeing 737 doors that is equivalent to but suggest it may be one or two.
