Are we all sure this is not just clever CGI? The jet pack pilot would need to have very impressive upper body strength to control the thrust of the forearm-mounted jet packs. Just a small unplanned arm movement might place the pilot in a position of losing control of the arm-mounted jet packs. Very few gymnasts can perform the "iron cross". Has anyone seen one of these operate for real instead of in pixels?
Just wonderin'.
