There's something about this that doesn't make sense. On the ground it's very easy to tell if someone's coming close with their fire. (Duh, that's why the tracers.)

Were those guys under ground control? Or were they over a free fire zone, with any target of opportunity they chose to bomb open to them?

What color were the tracers? (Not a definitive question, but could have given pause, unless they're all the same color now.)

How heavy was the weaponry being fired? Was it a realistic threat to their planes and missions, or such an urgent situation they had to react immediately?

How hard is it to figure out if you're being shot at with tracers if you're in a plane at 5,000 feet? Or if you're not? Or would you lose perspective, and a tracer travelling near horizontally might look like a long trajectory upward? I doubt that, but I don't know.

I think it's easier to say "Oh, well" when this happens every once in a while. And, it seems to me it's happening a lot. And not in the "heat of battle" or "fog of war". Wasn't it in Puerto Rico not too long ago a forward observation post got bombed in a training exercise?

What I'd ask is that someone, somewhere improve the control over these things. Clearly what they're doing isn't working, and "Oh, well" doesn't solve the problem
