From the WSJ article:
So the Iranians didn't get a drone with 2007 vintage electronics and sensors of very new ones. What a disappointment to them.Officials said the drone technology is constantly being upgraded, which would lessen the intelligence value of the drone the Iranians have.
That's a new meaning for the word "rescue", as far as I know.The Obama administration considered sending in a rescue team to secretly recover or destroy the downed drone before the Iranians discovered it, but ultimately officials dropped the idea as too risky.
