Continuity: In the beginning of the movie with the helicopter chase scene, there are two different makes of car used - a four door Nova and a two door Buick.

Factual error: DARYL steals an SR-71 Blackbird reconnaissance plane toward the end of the film. Conceding the absurd notion that a kid could fly it (computer brain or not), the problem is that SR-71 requires an in-the-air refueling shortly after attaining low cruising altitude. This is because the fuel tanks are designed to leak on the ground - the friction of high speed flight expands and seals them - and the afterburners required to get the plane up guzzle fuel. DARYL would have run out of fuel long before his flight ended, and the Air Force did not send up a tanker for him.

Factual error: While the problem with refuelling the SR71 is a real one for D.A.R.Y.L., he is never going to get that far. The SR71 had no self starters and required a trained crew with a starter generator mounted on a truck to get the engines going in the first place. D.A.R.Y.L. just pushes a button and away he goes. Not likely.

Other: During the eye exam, Daryl recites the eye chart but does not get it correct.

Continuity: The film starts with a helicopter chasing a car being driven flat out around a winding mountain road. At one stage you see that the nearside rear wheel has lost its hubcap. A few seconds later the hubcap's back.

Factual error: When you see D.A.R.Y.L. in the SR-71 Blackbird there are many shots of the cockpit. There are too many screens, in fact, the only "computer" screen in the Blackbird is in the copilot's part of the plane, D.A.R.Y.L. also did not have a copilot.

Plot hole: If the government guys could see Daryl in the cockpit, they should have known they could finish him off. If they launched a missile, he would either be hit by it or cook himself himself trying to outrun or outclimb it.
