In the half-decade since, they've changed the design proposal five times, they've changed big-name partners three times, have received no additional public commitments, and still don't know where (and entirely, with what) they're going to build this thing.
Would be so cool if this ever pans out, but not going to get excited until I see one lined up with a runway ready for a test flight.
