The Boeing “Phantom Eye” drone has flown. This is a remarkably tubby aircraft… because it’s fueled with low density liquid hydrogen. The eventual goal is to cruise at 65,000 feet for four days, with a 450-pound payload. It won’t be much good for carrying ordnance, but it might do ok in the high-altitude, long-duration recon role… in areas where it can get liquid hydrogen fuel.
