The other guy in freefall with him was tracking with him but not in a birdman suit, the birdman suit will out run another skydiver without one in a heartbeat so the video is misleading. I am very good friends with the west coast trainer and factory rep for the birdman. He says the guy maintained altitude for 30 seconds, stalled trying to climb, then engines out of gas. The west coast rep is also online for my small throttled rocket engines for a flight. The last test on the ground I got 60 lbs of thrust for 40 seconds, with one on each leg he would be able to actually gain altitude. Safety first so we are still doing some more testing before he flies them.
