A simple Tweet and they are gone.
They are survived by Wisk with whom they shared a relationship.
Physics is a tricky thing as many AAM companies are finding. I still believe these startups should have bet on cargo delivery of up to 150kg and built their technology and safety cases around that. Ramping up to manned flight as airspace, charging and autonomy are resolved.
If I had money to place, I would bet on companies that have started that way.
I do have a soft spot for Wisk though.
