A picture of the tail rotor of the chopper that the Navy Seals' Team Six detonated revealed unfamiliar features. Reports say it could be a new, secret helicopter.

When the Team Six members reached Osama bin Laden's compound in Abbottabad one of the choppers made a "controlled but hard landing," according to reports, probably due to higher than expected temperatures.

Temperatures affects the density of the air, and low density makes it harder for the rotor to sustain the weight of the chopper, especially if it was near its maximum weight (being packed with soldiers and fuel to fly in from Afghanistan). Abbottabad is about 1200 meters above the sea level, and altitude also affects air density.

The helicopter’s low-observable technology is similar to that of the F-117 Stealth Fighter the retired special operations aviator said. “It really didn’t look like a traditional Black Hawk,” he said. It had “hard edges, sort of like an … F-117, you know how they have those distinctive edges and angles — that’s what they had on this one.”

Watch this video. Shows parts of the helo picked up kids. And the residents claims their cell phones and other electronics were knocked and afterwards came back on. Sounds almost alien don't you think? Also they claim they didn't hear the helos coming in until it was right on top of them.
