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: In the scene where Jack is running beside the bus and breaks the window to get the driver's attention, you can see a reflection in the window of the bus of a cameraman running. In the next scene where the bus pulls ahead, the reflection of the camera is larger and more noticable.
Visible crew/equipment: When Howard Payne calls Jack in the bus and is saying he wants his money, etc, at the start of the next scene the bus can be seen with not only its front doors open, but the back doors open. A crewman is standing in the doorway of the backdoor, and it can't be Jack because when it cuts to him inside the bus he is standing next to Annie and he is telling her he is getting off the bus.
