One of the most impressive things about Sunday's raid in Pakistan, was the way the Navy Seals managed to penetrate deep into Pakistan without being caught by Pakistani air defenses. Now it looks like a super secret stealth helicopter may be behind this embarrassing security lapse.
The helicopter crashed during landing, and while the team took measures to destroy it before leaving, they missed the tail rotor section which had broken off and fallen outside the compound wall.
On Monday local children were seen picking up pieces of the silver loaded infrared suppression covering used on the tail rotor surfaces, before Pakistani authorities came and trucked away the remaining bits. Now there is concern that the highly classified materials are on their way to Pakistan's friends in China.
The military aircraft geeks over at Aviation Week say that it appears to be a previously unknown highly modified version of the H-60 Blackhawk, with special coverings designed to reduce its noise, radar, and infrared cross section.
What's not clear is whether just one of the stealth models was used, but that Tweeting Abbottabad resident shows us that the raid didn't go totally unnoticed.
