Engineering360: "VTOL UAS to Soar on Hydrogen Power"

With apologies to Shakespeare, this effort seems to be a bit of ''gilding the lily'' in terms of what it can/supposed to do. I mean the late Paul McCready and friends have pretty much already done the work on long duration, nibble atmospheric general purpose aerial platforms. Slap some UAV avionics, etc. into them and get on with the project; no need to reinvent the wheel; this project is mostly military-industrial largesse.
