Well this was rather cool. Not quite Iron Man but still impressive. I hope they keep advancing and developing this.
Ooooh I was just thinking that after I had posted....... "Superman!" I teared a bit during that scene.. BTW the theme of the movie "does a gun have a soul?" interesting. That was on the commentary track.
Oh, that's neat about the commentary.... that was a really good flick that somehow got undersold by the studio (forget which one produced it). Anyway, the real "iron man" (your vid) looks exciting. I also hope they continue with it.
At the moment he has 5 to 10 minutes of flight time, depending on the conditions around him, that's not bad for a start.
Weight vs fuel capacity, bigger tank = bigger weight which needs bigger engines etc etc etc jet engines are not known for their fuel efficiency either, but it's nice.
