Ehhhh.......
This was a project by Aurora Flight Sciences, which was bought by Boeing back in late 2017.
"Boeing Air Taxi" sounds good in the press, but I really don't think this was Boeing's reason for buying Aurora. Rather, I think they bough Aurora in order to get in on their DARPA and DoD contracts.
I'd wonder how much resources is Boeing really putting behind this "air taxi," compared to the DARPA/DoD work.
