Pakistani officials said today they're interested in studying the remains of the U.S.'s secret stealth-modified helicopter abandoned during the Navy SEAL raid of Osama bin Laden's compound, and suggest the Chinese are as well. 
  The U.S. has already asked the Pakistanis for the helicopter wreckage   back, but one Pakistani official told ABC News the Chinese were also   "very interested" in seeing the remains. Another official said, "We   might let them [the Chinese] take a look." 
 A U.S. official said  he did not know if the Pakistanis had offered a  peek to the Chinese,  but said he would be "shocked" if the Chinese  hadn't already been given  access to the damaged aircraft. 
 The chopper, which aviation  experts believe to be a highly classified  modified version of a  Blackhawk helicopter, clipped a wall during the  operation that took  down the al Qaeda leader, the White House said. The  U.S. Navy SEALs  that rode in on the bird attempted to destroy it after  abandoning it on  the ground, but a significant portion of the tail  section survived the  explosion. In the days after the raid, the tail  section and other  pieces of debris -- including a mysterious cloth-like  covering that the  local children found entertaining to play with -- were  photographed  being hauled away from the crash site by tractor. 
 Aviation experts said the unusual configuration of the rear rotor, the curious hub-cap like housing around it and the general shape of the bird are all clues the helicopter was highly modified to not only be quiet, but to have as small a radar signature as possible.
 The helicopter's remains have apparently become another chip in a tense, high-stakes game of diplomacy   between the U.S. and Pakistan following the U.S.'s unilateral military   raid of bin Laden's compound in Abbottabad, Pakistan, more than a week   ago. The potential technological advancements gleaned from the bird   could be a "much appreciated gift" to the Chinese, according to former   White House counterterrorism advisor and ABC News consultant Richard   Clarke. 
 "Because Pakistan gets access to Chinese missile  technology and other  advanced systems, Islamabad is always looking for  ways to give China  something in return," Clarke said. 
 The  Chinese and Pakistani governments are known to have a close   relationship. Last month Punjab Chief Minister Muhammad Shahbaz Sharif   concluded a trip to Beijing, afterwards telling Pakistan's local press that China was Pakistan's "best friend." 
  Dan Goure, a former Department of Defense official and vice president  of  the Lexington Institute, said last week the stealth chopper likely   provided the SEALs an invaluable advantage in the moments before the   shooting started. 
 "This is a first," he said. "You wouldn't know  that it was coming right  at you. And that's what's important, because  these are coming in fast  and low, and if they aren't sounding like  they're coming right at you,  you might not even react until it's too  late... That was clearly part of  the success." 
 Neighbors of bin  Laden in Abbottabad, Pakistan, told ABC News they  didn't hear the  helicopters the night of the raid until they were  overhead. 
  Officials at the U.S. Department of Defense declined to comment for this   report, and a senior Pentagon official told ABC News last week the   Department would "absolutely not" discuss anything relating to the   downed chopper. Several Chinese government officials in the U.S. and in   China were not available for comment. 
 U.S. officials have not  officially disclosed any details on the  helicopter, but President Obama  said it was a "$60 million helicopter,"  according to a report by The Washington Post. While the price tag on normal Blackhawks varies depending the type, none cost more than $20 million according to the latest Department of Defense procurement report.
