Interesting. Thanks.
One of the things people miss is that making this a 400 mile range and 1000 pound useful load requires no change except batteries. Assuming they designed it with easily replaced battery packs in 10-20 years it could become a useful vehicle. With our fleet containing a plethora of 75 year old aircraft (all with new powerplants?) - this could have decades of actual useful life.
The technology is, well, unremarkable. It’s the certification that is the news. (And clearly hype.) Still, Interesting.
