As posted above, the doors are much stronger than ever before. They should at $10,000.00+ a pop. The kevlar material is about as good as it's going to get.
The bottom line is, the airline employees and general public need to continue their vigilance for those that want to do harm. 99% would be taken care of if the word profiling wasn't such a dirty word.
It is interesting how as a crew we are frisked and subjected to these searches. Do you really think that a pilot needs a bomb to take out an aircraft. I guess they figure I need to be saved from myself. LOL

It's a lack of common sense and a show for the public. Enough said about the money being spent on the most expensive song and dance the airline industry has ever participated in.
