Correction: As Bruce Banner walks over to the Monitor, Natasha Romanoff follows him over and stands next to the desk. Bruce remains on the right of Natasha, before the explosion, after the explosion, and even as they fly through the glass windows Bruce remains on the right and Natasha remains on the left. When Bruce and Natasha fall to the ground, Natasha is still on the left and Bruce is still on the right.

Correction: If you watch closely, Iron Man falls back farther than the cab, far enough that in the next camera angle the cab can't be seen. The cab didn't disappear, he just rebounds off it far it enough that it isn't in the next shot.

Correction: While it's true a helicopter rotor uses reduced pressure above the rotor to produce lift, a rotor in a hovering [which is what the carrier is doing as it begins converting from sea to air] or vortex ring state, will produce updraft at the tips of the rotors, which is what is causing Banner's jacket to blow the way it does.

Correction: That's because there was no upper half of the tree to begin with. Look at the shot when Thor summons his hammer back after first hitting Iron Man with it during the forest fight. It comes back to his hand, and you can see behind him the jagged top of the stump; the rest of the tree had already fallen before Iron Man booted Thor through it. The shot where Iron Man kicks Thor through it does make it seem like there is a whole tree, because the shot isn't "tall" enough to show that the top of the tree isn't there anymore.
