The RUMOR from Heli-Expo was that they encountered worsening weather and perhaps waited a little too long to...what's the expression? "Land the damn helicopter." They chose what appeared to be a suitable site. It wasn't. When they did put it down, trees began piercing the belly of the ship (see photo) and it rolled over. Unfortunate accident. But hey, accidents happen. Just glad the crew wasn't more seriously hurt or killed. I'm sure there are other UH-60's out there that can substitute for this one.
