10 points. (the second silent hawk drawings) the other options mentioned above are way off, but this one fits the bill.
Was it fully operational, still a test phase, a XCH-60 or YCH-60? Guess time will tell.
Indeed a bit painful (utter embaressment if you will) that they lost it in a foreign country,
(way worse than an ancient RNLN lynx recently in Lybia).
Brings back memories of a painful failure in an action some time ago in Persia / Iran and also of the time when they left a downed secret stealth F-117 'Sitting Night Duck' for the opponents in Yugo-land.
