747-400 doors
Upper deck doors as I recall are locked...or at least the opening lever is. Lower deck plug type. (There is a weird and wonderful procedure for smoke removal that involves opening them in flight)

Some time back indeed. If you are worried about ZF being a closet terrorist I must observe that he is taking his time as he has been with us on PPrune for over 12 years. A true 'sleeper'?

I guess some are just fascinated with doors.

ZF may not be a sleeper but I doubt the wisdom of posting all this here and now. ISIL are quite sophisticated and shouldn't be spoon fed by Jammed Stab who should erase his 2 posts IMHO. Be careful - the only people who need to understand that stuff are qualified 747-400 aircrew - not the general public.

Omg
I m sorry to have generated such much suspicious !!!!!!
Let me re frase the question
Above which speed the mechanical interlock door Bar ( if any) automatically is inserted to prevent the total opening of the door in flight if necessary to evacuate the smoke if any ?
I read it somewhere 20 kts or I may have fabricate it into my ram memory....thank you BOAC for observing the facts..I appreciated and peacefully go back to sleep.
