I just saw a picture of an Air Canada B767. The front door at the left of the aircraft was open but I couldn't see the door itself. I have seen this on some MD-11's too, where the door didn't went upright just going up. Two questions:
Are these kind of doors available on all aircraft?
When there is an emergency, are these doors as easy to open as doors on eg the 737, turning outwards and the A340/B777 just gliding sidewards?
