Thunderhawk's right gull-winged door is shot off by Jackhammer. Later it is still missing in an overhead shot, but back on the car when Thunderhawk passes Shark. After that, it is missing again.
Immediately after the first time T-Bob is squashed by the Gravity Weapon, he is seen sitting in the back of Thunderhawk without any damage.
The same shot of Thunderhawk transforming into jet mode and taking off is used thrice. The second time, the footage is flipped horizontally, and Matt Trakker can be spotted behind the wheel on the right side of the car instead of the left.
