Rumor has it the Chinese helped the Iranians interfere with the comms.
Here's some pics of what the Itranians showed compared to what we have.
Looks like they got one, and then when the people on the ground wanted to strike the wreckage theuy were over-ruled because someone didn'tr want to further inflame the Iranians.
My thinking would have put a JDAM on target and if the Iranian Revolutionary Guard was already there, all the better. it's past time we paid them back for killing US soldiers in Iraq in border incursions there.
Looks like a real one.
I would have thought that there would be a self destruct fail safe that would blow it up if communications was lost.
Too bad the Chinese and or Russians will be examining the technology.
