The Fairey Rotodyne was as indicated well beyond its time in concept and technical development.
Unfortunately it was also well beyond the understanding of those who could have sanctioned development towards a fantastic use both in civilian and military areas.
As always the British invent a really great concept and then manage to shoot themselves in the foot when it comes to taking advantage of the idea.
We invented the movable tail plain that advanced the ability of controled fixed wing flight above Mk 1, guess what, we gave it to the US, FACT.
