While they are leaving for the mission we see Hunter walking through the hanger with Gen Byrne-White to get to his plane when he's stopped by Egg. In this scene Hunter's helmet is attached to a hook on his right hip and he has some sort of equipment attached to a strap running down his left thigh. When the scene changes to Hunter walking outside his is now carrying his helmet in his left hand and the thigh extensions that he had in the previous scene are now gone all together.
In the ending to this scene when Zara kisses Hunter both the thigh straps and helmet are gone.
A split-second before Hunter jumps his motorcycle over the SUV, Byrne-White and Zara are looking at Hunter's approach out the left window. The next shot shows the SUV parked between two boulders, left & right, as Hunter jumps over them. The boulder to the left should have blocked their view of Hunter's run.
