I don't know if there's an FAA standard for the reinforced cockpit doors but the new ones on DL's aircraft would take a bit more than a well placed foot IMO.
The doors are open when the plane is at the gate and they secure them to the lav door on certain aircraft types.
if you have to use the lav, you need to swing the cockpit door with the lav door. You can feel the weight of the door and it's gotta go over a hundred pounds. Plus it appears to be over an inch thick and made out of some lead-like substance. And there's a 1" lip that overlaps the frame.
I don't want to meet anybody in a dark alley who's capable of kicking one of these doors down.
