YES, but it is unlikely that a person opening and closing can do it. But try lifting the aircraft door up with a catering truck, or a set of steps! The hinge mechanisms of most doors are very complicated.
To open the door you have to move the stop pads apart. Older Boeing doors 707 727 737 747 757 are all similar the door moves horizontally in to the aircraft and then out. Newer Boeing doors 777 787 and all Airbus doors the door is lifted about an inch and then goes out. In all cases the person moving the handle is physically opening the door.
The old Boeing door (still fitted to new 737NG) is easy, if you are standing in the right place, but to open and especially close the fwd doors on a 737 needs a knack. Most airlines will not allow a flight attendant to close a B737 or B757 door from inside. There is too much force required as you are leaning out the door.
I like the A320 series. I can open it from the outside single handed, just lift the lever and pull.
The worst is the B757. When closing from outside you have to try and engage the butterfly handles as the detents get to the right spot. Takes practice and it is easy to jam the door 90pc closed.
In an emergency the door is opened from the inside with the slide engaged. This makes the door a lot heavier to open than normal. B747 757 and all Airbus have a small nitrogen bottle that is fired to push the door open. B737 and the older B707 727 do not. B737 cabin crew meeting their first emergency opening of the fwd doors in engaged mode have been known to fail, and need help because the door is so heavy. This is still the design on new 737NGs.
B767 and Tristar doors open up into the ceiling. The doors are balanced on a massive spring, so in emergency when the slide stays on the floor, the door is suddenly much lighter and is launched skywards. You need to inspect the up stops after this!!
