For the OP:
A bit over 36 years ago, I saw a nearly identical film while in Navy Flight Training, and we were quite awed by this
PR piece. Neat tech.
Here's a news flash for you. The Rotary Wing industry has not been sitting on its ass for the past 36 years. At the time, this program had much promise but as with all programs the devil is in the details, and there are competing programs, and even with Uncle Sam only so much money for the rotary wing bubbas.
If all that an aircraft had to do was be cool, all that any of us on the planet could fly would be P-51 Mustangs and F-4 Phantoms, and Cobras. There'd be no other aircraft left.
So, yeah, looks cool. There's more to it than that. And in fact, it's complicated, by at least an order of magnitude more than a fixed wing aircraft. Suggest you go and find a nice RAH-66 Comanche video and take a cup of coffee and swoon. That too was a really cool helicopter. I got to see one of the prototypes fly. Cool is an understatement.
But it didn't reach FRP for
reasons.
