At least two of the helicopters used in the raid on Osama bin Laden's compound seems to have been a new stealth design, according to several reports emerging from the scene. The use of such helicopters may have been key to the success of the operation that resulted in bin Laden's death.
A huge part of the operation was crossing the border between Afghanistan and Pakistan to avoid detection by the Pakistani military and get the Navy SEALs into Osama bin Laden's compound.
In the attack, one of the helicopters was forced to land, and was destroyed by the U.S. Navy SEAL team that eventually killed bin Laden. The tail section was separated and soon photos of it were making the rounds on the Internet.
The following are photos from the compound.
