That wasn't shot down with IR manpads though. The likely suspect is a vehicle mounted radar based system. Most manpads don't pose a threat at reasonable cruise altitude. They're more of a takeoff/landing threat. There's a minimum warhead size to do the job and a minimum fuel required to get it to a given altitude. Anything that can reach an airliner at a typical cruising altitude is going to be vehicle mounted for the foreseeable future.
