I strongly disagree with you. There is no point locking the flight deck doors. On one of the hijacked planes in the USA the hijackers were unable to break down the locked flight deck door, so they started stabbing one of the stewardesses until it was opened. Can any of you seriously say you would not open that door if you got an intercom from a girl saying she was being stabbed? Or, they could say they have a grenade and will blow up the whole aircraft if you don't open the door. They will assure you they will not harm you if you do open it - maybe they DO just want to be 'taken to Tehrain' etc and it could be a 'conventional hijack'.
There are also too many reasons why access is essential to the flight deck:
1. In an emergency the pilots may need to go down the back (gear lock viewers, burning smells etc).
2. In an emergency the No.1 must be briefed. This is far better face to face from a CRM point of view.
3. The toilet is outside the flight deck on short haul aircraft.
4. Pilots require food and drink from the galley.
EME - where EXACTLY do you propose putting a toilet inside a 737 cockpit?! There isn't enough room to swing a cat in there. There are 1000's of them worldwide, each capable of being used like in NY. The cost of redesigning them would be prohibitive and it wouldn't achieve anything.
