Ever tossed an ant of a balcony? they float...same concept
Not that I'm an expert. But apparently with smaller objects it doesnt work like that. They explained somewhere why he can survive at that speed. The suit he wears is also what will help him reach that speed. They have already reached faster speeds than the standard one that you are mentioning. Don't know the technical name. He is not reaching the speed vertically. He will accelerate like a plane.
