There was an accident in the North Sea several years ago, with a Super Puma taking off in a very strong wind, and then turning downwind - the aircraft crashed into the water, and if I'm not mistaken, one of the causes was the turn before the aircraft had sufficient airspeed.
Unless I'm mistaken (and that certainly could be the case), my understanding of that crash was this:

Puma, at night/strong wind/low weather, going from one platform/rig to another directly behind. The crew took off, did the 180 successfully, but as they came screaming by the intended platform on the downwind at low altitude, the PF who was obviously looking outside at the rig and not at the ASI, decelerated causing what is believed to be the dreaded vortex ring state at which point they impacted the water.

At least, that's how I remember it.

I think Overpitched gets confused because wind is seldom completely steady like out over water. Gusts/up/downdrafts add to and detract from performance.
