"Um, that part of the helicopter is like none i have seen," wrote one of my Twitter followers yesterday. "And i worked on MH-53Js in Air Force Spec Ops."
The Army Times reported that helicopter used stealth technology like that of the F-117 stealth fighter, and also used special baffling to hold down on the sound that the helicopter would normally make.
While U.S. officials have not commented on the record about any stealth technology, they did not try to hide the fact that one of the two helicopters used in the raid was blown up after Bin Laden was killed.
"During the raid, we lost one helicopter due to mechanical failure," said a Senior Administration Official during a briefing after President Obama spoke to the nation on Sunday night.
"The aircraft was destroyed by the crew and the assault force and crew members boarded the remaining aircraft to exit the compound," he added.
But they didn't want to follow up on that with any details later in the same conference call.
"My question would be, what was the type of the helicopter that failed? asked one reporter.
"Can’t go into details at this time," said another official.
It's no real surprise that U.S. Special Forces Command would have had some high-tech equipment - but if not for mechanical troubles on this raid - no one would have known anything about it.
