All you really need is two people and a camera plus some editing systems but that does not need to be great
Have one person jump and take a picture of them in the air then move him forward and take a shot of them in the air again and keep doing it until you are satisfied put the shots together and it looks like there flying.
too make the sliding around effect take a picture of them on the the ground then move a bit then the same then move a bit then the same etc
The less you decide to move between each shot will make it look more realistic
Enjoy watch the video for an example!
