Anyone have the real story on the F-35 getting hit?

 Many have talked about it but I just don't get it.

The F-35 got hit from the ground.  Some are saying ground fire, some are saying a heat seeking missile, no one seems to know for sure.

Gotta alot of people on this blog that are still cued in.

What was it?

I imagine if it was a golden bb then that's all pilot error (I mean the F-35 is supposed to shit different from an A-10 right?).  But even a heat seeking missile is kinda concerning cause we're supposed to have countermeasures against threat missiles right?
