According to a report from the Shanghai Evening Post, the Pakistani officials claim that they are interested in studying the remains of the U.S. military helicopter that was damaged in the raid on the bin Laden compound, although the U.S. wants it back. Pakistan may invite China to participate in the study. Based on the pictures, aeronautics and military experts believe it is a modified stealth helicopter.
