Visible crew/equipment: When the bus is about to jump the bridge, you can see that the bridge is flat, apart from the broken part, but when the bus jumps over the bridge, there's wood and stuff piled up at the end, making it "kick". (01:03:35)
Visible crew/equipment: When the police officers are attempting to rescue all the passengers on the bus while at the airport by driving up beside the bus, at one point you get a front camera angle shot showing the people jumping out of the bus onto the police vehicle. If you look closely, you can see the camera man sitting on his chair reflected in the window of the open bus door, he is wearing a white shirt with sunglasses.
Visible crew/equipment: When Jack is running beside the bus and breaks the window to get the driver's attention, there's a reflection in the window of the bus of a cameraman (wearing a baseball cap) running alongside the camera. In the next scene where the bus pulls ahead, the reflection of the camera is larger and more noticeable. (00:34:35)
Visible crew/equipment: The first bus explodes, and the traffic on the road mysteriously disappears. If you look down the road, there are construction barriers blocking off the entire road, which would not allow any cars to drive through.
Visible crew/equipment: In the scene where the bus jumps the gap in the freeway, as the bus lands, the interior camera jerks down and we clearly see the cameraman's brown shoes.
Visible crew/equipment: In the scene where the bus is exiting the highway on that sharp curve there's a medium shot showing the bus from the driver side. Look closely at the driver, it's either a really ugly woman or that's a man in a wig driving the bus. (00:47:04)
Visible crew/equipment: During the scene where the bus takes the really sharp curve it kind of goes over on two wheels - if you look closely, you can see some sort of lift under the bus obviously causing it to tilt so far sideways. (00:50:10)
