Black Hawk stealth helicopters seems to be used in Bin Laden's assault

At least one of the helicopters used for reaching the Bin Laden compound in Abbottabad was a modified stealth version of the Black Hawk. Military and intelligence US agencies have refused to comment about the use of stealth aircraft in this mission. But the photographs of the helicopter that navy seals blew up (after it was damaged in a hard landing ?), indicates modifications on the tail section which could improve the stealth properties of the helicopter (click on image for enlarge).
