For anyone who is a nervous flyer, you can at least scratch one item off your list of fears: It is physically impossible to open an airliner door in flight as the pressure differential between the cabin and outside air creates a force of several tons holding the door closed. The Incredible Hulk couldn’t open it.

Wonder what's in those cigarettes he smokes....hmmm...

Here's a physics question:

If you were to get out of a jetliner and walk out onto the wing of it while in flight at 35,000 feet, what would happen?

Would the wind immediately blow you off the wing?

Or would you be able to "ride" the plane like the guy in the picture here (obviously photo-shopped - or is it?).

Are you sure of this? I would think that the higher pressure would be inside the cabin and the lower pressure would be the outside air, making the pressure differential a positive pressure from inside the plane to the outside of the plane. If you did open the door, you would essentially get sucked out.

The Hulk would just open a window if he wanted to smoke anyway.

The door has to come in first, before it can rotate and swing out.

Math time. Door 50" wide x 75" tall= 3750 square inches. Extremely low side of the differential pressure would be at least 8 psi. 30,000 pounds.

Something close to that.
