Murexway,
I'm sure with a few seconds on Google the "knuckleheads" could find the information easier than trawling through PPrune ! Hell, the "knuckleheads" probably have friends (either genuine or "recruited" with a bit of cash) who are engineers, line pilots or door manufacturer employees to give them the information !
As I said ... "security by obscurity is not security". If you built yourself a house in the middle of the Australian outback, with no locks on the doors..... told nobody you did it, told nobody what was inside it but placed a few million dollars worth of gold bars in it ..... would you sleep at night if you lived a few thousand miles away ? It's safe right because you've secured yourself by obscurity ? No, of course not. You would layer the security wouldn't you (CCTV, a safe, an alarm system, a guard etc. etc. ) ! Same goes for the aviation industry and its security.
