While many still reasonably view these aircraft as answers in search of a question, there is no doubt that Archer appears to be making rapid progress.
Lots of other companies are doing the E-VTOL thing and promising much but showing little. It may be that much more is happening quietly in the background. But much like the small-sat launcher market (see HBO’s ‘Wild Wild Space’), there will likely be few winners here, and much capital washed away in pursuit of unrealized visions of an unlikely future.
