I can't verify this, but it sounds about right.....the Stinger's smarter than the raghead. Hamas terrorists smuggled in portable anti-aircraft Stingers in hopes that they could use them to down Israeli aircraft during Operation Cast Lead. "We were disappointed by them, and they were found to have been useless," a Hamas source said. The weapons wouldn't operate due to an embedded identification system, reportedly of Israeli issue, which recognized IAF choppers and drones, displaying the message "Friendly Aircraft." Gotta love it!
