Came across a timeline where in 1973, the US Army evaluated Fenestron technology n the then 2008 50 Years of Eurocopter USA book 'Above All'. Also saw this photo on FB, taken in March 1973 at Fort Rucker (?). It is an Aerospatiale SA341 Gazelle parked in front of the Army Aviation Test Board. It be interesting to see what the AAOTB thought, I would not have thought it as a potential OH-58 or -H-6 replacement at the time.
Cheers
