If you reverse at speed in a J2 the door stop will come through the back window and leave you hanging there...
And I can also confirm the door locking bars on a HAS can slice through both the inner and outer skins of a bowsers tank full of fuel ..... I can also confirm a Flight Sgt with a sandbag is no Little Dutch Boy... however he did try, even though the hole was longer than the said bag by some margin..
