America thanks the Brit empire for doing all the hard work. That Harrier deal was pretty good to. So was that angle deck thingy, the steam cats, the mirror landing system, and.....oh yeah, Aircraft carriers to. We've managed to improve upon them all, and have put them to good use.
I had no idea this Brit AC existed, but US aviation research was a huge sponge at the time, getting all they could from any source........which is logical actually.
Don't forget what happened with the Avro Arrow to...........NATO suffered because of that mistaken cancellation.
