As an aviation enthusiast, I'd happily pay $1000 for a window seat on that (demo) flight.

Is it camera angles or is that actually taking off almost vertically there?

Press calls it "Near-Vertical Takeoff".

I think they need to develop life-saving technologies before doing things like that. Because one small mistake can lead to the crash.
