Could the Bin Laden raid have revealed a secret new helicopter?

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.

So what machine exactly experienced the hard landing described above? Short answer: we don't know for sure. Long answer: It seems that the tail rotor visible in the picture belongs to a highly modified version of the H-60, the chopper of choice of the special forces for more than 30 years. Aviation Week doesn't beat around the bush, claiming: "A previously undisclosed, classified stealth helicopter apparently was part of the U.S. task force that killed Osama bin Laden in Pakistan on May 1."

I was wondering why and how the helicopter crashed when everything else seemed to go flawlessly.

I've been in helicopters, including one that made a (very) hard landing, so I know they're just a tad unreliable. But why does this always seem to happen whenever we're engaged in some supersecret national existentialist raid?

ABC suggested that parts of the wreckage are already on their way to China.

Very small, from that perspective anyway.

Not many people fit in any tail rotor...

The tail survived cos it was supposedly on the outside of the compound

Yahoo was running this story and they are v. right wingy

The first requirement of any aircraft is that it, you know, remains in the air.

sound of the helicopters did not alert people in the compound.

I have the theory that, as here in LA, that area probably had a lot of helicopters flying overhead from time to time so that Osama Bin Laden did not suspect anything unusual.

But it is also possible that the helicopter was quieter than expected.

I, of course, have no clue -- just theories and perhaps sometimes an overactive mind.

These kinds of questions fascinate me.
