If doors off and reacher are snivelling lackeys and probably in bed with Eurocopter, then why isn't anyone accusing BR71 of being a Bell / Textron plant, trolling for business for his re-engineered Hueys? You can't have it both ways.
The reason the Black Hawk exists is because of the lessons learnt and the vulnerabilities discovered in the Huey, arising from Vietnam. MRH90 / NH90 is a newer take on this twin turbine, AFCS, crashworthy, very powerful style of aircraft.
Everybody loves the Huey, but no-one really wants to take it to war. They built over 10 000 of them, and there are not many left around. Why is that? Could it be that things have moved along since 1958? An EH Holden with a nice modern engine will still have its butt kicked by a new Commodore.
