Corrected entry: Payne tells Jack he wants the money left in a green bin on the northeast corner of some intersection. Then later we see Payne looking out a window at the drop bin. If that's the northeast corner, then the shadow of the bin indicates the sun is shining from due north, and quite low to the horizon. That would never happen - certainly not in Los Angeles.
Corrected entry: At the airport, as the last bus passenger is crossing to the rescue vehicle, the right rear tire of the city bus blows out. The bus immediately veers to the left, and Annie pulls the wheel to the right to try to keep a straight course. However, a vehicle will always veer to the side with the blown out tire, which in this case, should have been to the right. (01:24:50)
Corrected entry: Our heroes steer the bus toward a gap in an elevated exit ramp even though we can see in a wide shot that they have at least two alternative routes, one of which is completely unobstructed. It appears that the only possible reason for taking the route that they chose could be to film a jump scene. (01:02:35)
Corrected entry: At the end of the film, a tape loop is made of the camera inside the bus to trick the villain to think that everybody's still on board. With the video equipment shown, it is simply not possible to do a seamless loop in a flick of a second.
Corrected entry: When Howard is talking to Jack on the payphone, after blowing up the bus that Jack's friend was driving, Howard says, "I want my money by 11am." Later on when Jack is trying to defuse the bomb when the bus is in the airport, Jack's watch says 5:01pm. We know the time's right as he checked it earlier. (Frame by frame required.) (00:29:10 - 01:11:25)
Corrected entry: Howard Payne says to Jack at the beginning when they are talking on the phone, that if the bus drops below 50mph it blows up, so how come when we finally see the bus explode at the airport we see the speedometer on the bomb explode at 50 not below it. (00:28:40 - 01:26:55)
Corrected entry: Soon after Jack gets on the bus, Howard can see the bus on the news. Why is the news at this stage covering this? The only thing that has been suspicious is someone from a car coming from a car onto a bus, but what has happened before this that makes this newsworthy? Looks like regular traffic is flowing up to this point. (00:44:00)
