"It's bad — they'll have everything"

"...Although the Sentinel's capabilities remain largely classified, it is believed to carry the latest in cutting-edge cameras and sensors that can "listen in" on cellphone conversations as it soars miles above the ground or "smell" the air and sniff out chemical plumes emanating from a potential underground nuclear laboratory.

Ever since it was developed at Lockheed Martin Corp.'s famed Skunk Works facility in Palmdale, the Sentinel drone has been cloaked in tight secrecy by the U.S. government. But now the drone that the Iranian military claims to have brought down for invading its airspace might be made far more public than the Pentagon or Lockheed ever intended.

Another U.S. official with access to intelligence said that losing the Sentinel is a major security breach. The official, who was not authorized to publicly speak about the information, wouldn't say how the drone fell into Iranian hands, but confirmed that the downed drone was largely intact.

"It's bad — they'll have everything" in terms of the secret technology in the aircraft, the official said. "And the Chinese or the Russians will have it too." ..."
