It’s entirely on the Eagles. From their fucked up VID forward.
Had their been no VID, then maybe include everyone else. Once they went in for the one ID that trumps all others, and fucked it up in both how they did it and and what they came up with, then it became squarely on them. No excuses. At that moment, the other factors just became chaff to try and shift away from the true fault.
The even bigger issue was the salivation to kill two helos that are tooling around in trail doing nothing, no hostile acts, just flying around; even if they were Hinds. Had the desire to kill them instantly, now, been tempered just a bit considering their doing nothing besides flying, there may have been another chance to figure out that they are actually friendlies. The Eagles saw what they wanted to see, and killed what they were dying to kill. And some O-3 taking a nap in an AWACS, would’ve made zero difference at that point.
