Terminator 3 Sucks

Lady Terminator, midway through the movie, due to some clever physics calculated by the t-800, gets a heavy duty mobile crane slammed right on top of her. She is slowed down, but neither stopped nor permanently damaged.

Later, in the climax, she is pinned down and defeated by a helicopter. A Helicopter. A flying vehicle weighing at least one order of magnitude less than the crane simply due to it's need to function.
