Well, surprise, surprise! Hopefully the snake oil salesmen will pack their medicine bags and leave town for another 10-20 years. What a complete waste of money and effort on a pointless technology. It should have been spent on hybrid rocket engines at the cutting edge - or even on a British built light aircraft to replace the aging Cessna/Piper fleets.
Thank goodness no one was seriously hurt after 2 accidents with this pointless gas bag...
