Visible crew/equipment: When the credits are rolling, a crew member in a gray shirt on the lower left portion of the screen can be seen waving extras into the street. (01:51:05)
Visible crew/equipment: When the bus is traveling on the shoulder, a camera truck is visible to the extreme left immediately before Annie asks whether or not she should stay on the highway. (00:46:35)
Continuity mistake: When the crane breaks free from its bolts and starts flying towards some ventilation windows, it obliterates the upper pair. However in the next view from within an air duct, both of these windows just swing open freely as the crane busts through, and yet they barely appear to have suffered a scratch or bend in the process. (00:15:00)
Revealing mistake: At the off-ramp's red light Jack stomps on Annie's foot to keep the bus going, but she screams in pain before her foot actually gets crushed. (00:47:15)
Visible crew/equipment: Just after the bus has got on to the empty freeway, there is a long shot of the bus driving off. In this shot, the camera's shadow can be seen to the extreme right of the shot. The shadow is faint, but it is there. (00:51:30)
Continuity mistake: When the crane is torn out of the floor and flies towards the ventilation window, from a shot behind, the holes on the base (where the screws used to be) are gone.
Continuity mistake: In the scene where the Pacific Courier Freight plane gets blown up, you can see that it is being towed alongside another plane, and some people standing/walking around next to it. In the next shot, where we see the camera moving closer and closer to the plane from the bus's perspective, the runway the plane was just being towed on is gone, as is the plane it was going past a moment ago along with the people. There was no time between shots for the plane to have been moved so far away. (01:30:35)
Continuity mistake: In a camera shot from behind the bus, it shows Traven moving the Jaguar in front of the bus. In the next camera shot from the front, it shows Traven moving the Jaguar again in front of the bus. He'd already completed the move in the previous shot.
Revealing mistake: When Traven is walking back to his car before the first bus explodes, as the bus drives past him, you can see from the shadow it casts that the bus isn't driving straight on. It turns the corner behind his car. Obviously a prop bus is further down the street and that is the one that blows up in its place.
Visible crew/equipment: In several shots of Tuneman in the Jaguar, you can see camera lights reflected in his sunglasses.
Audio problem: When the first bus blows up (the one that Bob was driving) you can hear the explosion before the bus actually blows up.
Continuity mistake: At the beginning of the movie we see Keanu Reeves taking Jeff Daniels "out of the equation" by shooting him in the leg. We realise it's a serious injury as he requires the use of a cane when receiving his medal. However later on in the movie when they move in on Dennis Hopper's home, which takes place the next day, Daniels is part of the assault team and has no cane, no limp and is obviously very mobile.
Continuity mistake: When Jack drives on the shoulder, honking his horn to let people know that he's coming, he's pressing on a silver ring, which is the horn, but in the next shot, it's gone. While the ring only covers half the wheel, as he's going almost entirely straight it should always be in the same position. (00:31:35)
Plot hole: It is never definitively stated if the bomb is tied directly to the axle, triggered by the speedometer instrumentation or throttle. Regardless, as long as the wheels keep spinning above 50mph the bomb will not explode by design. This means that if you lifted the wheels of the bus off the ground or you bottom out, you could keep accelerating without any speed at all. This could be accomplished in any number of ways. One example would be driving on grass and keeping the tires spinning.
Suggested correction: And that would accomplish precisely nothing. They know Payne is watching them and he explicitly stated no-one is allowed to get off the bus or he will detonate it, only making an exception for the injured driver. What good is finding a way to keep the wheels in motion if everyone is still stuck on the bus?
The mistake is suggesting that you basically find a way to stop the bus but keep the wheels spinning such as grounding it on a hill. Then while the bus is stationary, just (I'm assuming here) put a weight on the accelerator to keep the wheels spinning and then everyone just hop off and walk away. However, you're correct in that Howard is watching the live feed so would just blow the bomb when people got off.
I fully understood what the entry was suggesting, but Payne's demand that everyone stays on the bus under penalty of detonation voids it. Even if that wasn't the case, finding a way to somehow stop the bus but keeping the wheels spinning (such as lifting it with a helicopter) would be a logistical nightmare in that scenario. Their plans to drive on the otherwise unoccupied freeway and then circle the airport runway were much more practical.
Factual error: The bomber wants his money by 11 am. The sun should be almost directly overhead. Why then are there late afternoon-early evening shadows at the end of the film?
Revealing mistake: When Jack is fighting Howard on top of the train, for a second or two, you can see a blue screen behind Howard instead of the regular background. Someone forgot to add the chroma key background in post. (01:44:05)
Visible crew/equipment: As the bus goes down the freeway, there's a shot of the police chopper following the chase. The movie camera chopper is seen above and to the right of the police chopper that is referred to as a news chopper, but isn't seen again.
Visible crew/equipment: After Tuneman's Jaguar hits the water barrels, a film crew's truck can be seen out the bus's rear window just before the shot cuts away. (00:40:05)
Continuity mistake: After the first bus explodes, Jack ducks for cover near his Bronco. Soon he looks over at the burning wreck and stands up - but notice that he's still crouched down in very next shot. (00:27:50)
Revealing mistake: When Ortiz first sees Jack stranded beneath the moving bus, he lifts his head to tell Annie. But the pavement, as seen through the bus floor's opening, is completely motionless. (01:17:25)
