like that, a little bit cruder, in 1939 a long, long time ago there wouldn't have been a Gossamer Condor, there wouldn't have been an Albatross, a Solar Challenger, there wouldn't be an Impact car, there wouldn't be a mandate on zero emission vehicles in California.

Human powered airplane Gossamer Condor sort of started me in this direction in 1976 and 77, winning the Kremer prize in aviation history, followed by the Albatross.
