Somebody <should> get fired at Boeing. There is no excuse for this sort of thing, none whatsoever.
This could have been so, soooo much worse. Imagine this door plug separating at, say, 35,000 feet, with passengers out of their seats or flight attendants in the aisle doing the beverage or meal service. How many passengers or crew members would have been expelled from the airplane? It's too horrible to think about...
Somewhere around my house, in my modest collection of WWII aviation literature and books, I have magazine ads that Boeing used to run in Life and Look. Featuring heavily-damaged B-17s, the text of the ads touted the strength of Boeing aircraft...the truss construction of the wing spars, the self-sealing fuel tanks, the autopilot and redundant controls...and promised Mr. and Mrs. America that their sons were going to war in the finest airplanes in the sky. The ads went on to promise that when the war was over, that same Boeing expertise and technology would be used to make civilian airliners...
I have no doubt that right now, tonight, William Boeing is spinning in his grave...
