Once upon a time, I talked to some of the Bell test pilots and engineers who worked on the HSL program, an early 1950s tandem powered by a P&W R-2800 engine for ASW. When I said HSL, their next sentence included the words “noise” and/or “vibration”. It was quite a learning curve for them, but the joint experience that resulted from solving all its problems forged them into the team that created the HU-1 (not a typo, nephews; that’s why its nickname is Huey).
