The whole point of Terminators was that they could look and act like humans so they can infiltrate. There were various flying war machines in Terminator movies. Notably the opening shot of the first Terminator movie shows a flying platform killing people with lasers, and in Terminator 3 there was an experimental drone in one of the labs in the facility where Robert Brewster worked.
