Compressed air backpack...

[Erik]

Some guy straps a bunch of jets filled with what appears to be compressed air to the back of his backpack. He then releases the air sending him hundreds of feet into the air.

I think this is fake. It appears that he is moving around when he is in the air, but his trajectory remains unchanged. Was there some kind of a spring-loaded ramp or something under him?
