Continuity mistake: When Talia is first killed, while in the Cadillac, the passenger door is blown off. When Adam drives through the water there's an inside shot of him and you can tell the door is back on for the scene. After going down the stairs there's the same inside the car shot of Adam and you can see the door is missing.
Continuity mistake: When the Cadillac crashes through the neighbor's fence, it loses the rear driver side hubcap. Later, in a few shots of the tires, the hubcap is back on and then off again.
Other mistake: When Adam lands his chopper on the rooftop, he shows his charter contract as proof he is supposed to be there. There is no information filled out for the dates on the contract.
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.
