Revealing mistake: When Arnold is back at his partner's house and the guy comes in shooting, watch the 1st shot as Arnold dives out of the way. The film editor's timing is off because it appears that he's jumping into the gun shot. (00:56:25)
Chosen answer: The company did not intend to kill and clone the pilots. The activist killed Drucker and Hank Morgan, they wanted to clone everyone that was killed so nobody would know it happened. The only reason they cloned Arnold was becasue they thought he was the pilot.
