In the beginning of The Bourne Legacy (2012), JeremyAaron Cross was in training in Alaska, and met with another agent. There's a scene: when JeremyAaron ran out of the cabin, and the missile destroyed the cabin. He immediately put some tinfoil (can't see clearly, I guess so) close fitted to his body, and then the drone canis no longer able to track him. In reality, iswould this trueactually work?
