I'm not sure about "operational inputs" and "front-line experience", as teeteringhead mentions. My rotary basic was over a half-century ago
, and I'm sure things have changed out of all recognition, but we were just taught to fly the aeroplane. Yes, we carried crewmen, went into clearings, did mountain training at Valley, where we also did winching work over the water. However, a long way from "front-line". So I guess we never had "creamies" on rotary; just at BFTS.
