It seems the Hamas don't like the stinger missiles they stole from the US. Every time they tried to fire 'em at Israeli aircraft, a message appeared on the display stating, "no-fire, friendly aircraft!" Now, while that pissed-off the Hamas, what really pissed them off was the fact that when they insisted on firing one anyway, it locked onto their own gun crew and blew their Hamasses clean off!

Thank God, and thank you too, Raytheon corporation...
Hi Rod,
While certainly amuzing, the story holds very little technical merit. "Identification of Friend or Foe" (IFF) does not rely on visual indentification or a database of "US made aircraft" to determine if an aircraft is friendly or not. Codes are inserted into the IFF devices on both the missile system and aircraft, usually on a daily basis, and through the use of RF energy the gunner would "interogate" the target. If a proper response code is returned by the target it would be deemed friendly. If the wrong "reply", or no reply is returned the aircraft would be deemed unfriendly, or at least suspicous (it could be a friendly aircraft with no, or the wrong codes inserted). These encrypted codes are extremely sensitive and controlled and the odds of Hamas having the codes at all, never mind the right one for that moment are extremely low. If in fact they were capable of getting these secure keys, the devices to install them, and the knowledge of how to make it work, then it should be presumed they wouldn't be dumb enough to use them in a way that would prevent the use of the missile. Then of course you always have the option of just turning it (IFF) off on the missile system. BTW, the pilot would be aware he was being interogated also, regardless if the right keys were inserted or not. That in itself would not the negate the story but goes to the point that proper use of IFF equipment is rather complex and doesn't just happen by accident.
As far as engaging their own gunners by accident, that's probably a bit of a stretch also. I guess conceivably it could happen but once again the odds of it happening are pretty slim. Infrared missile systems are designed to work in a specific fashion and engaing ground targets, intentionally or not, is not easy to do. Without getting into the weeds, the function of IR missiles is physics based and engaging targets other than those that are airborne is in contridication to how they operate. Not impossible I guess, but once again the scenario described in the article is unlikely.
An interesting story none-the-less.
