Carrying live ammo during an exercise? That's a new one on me.
We often flew with live weapons. We had dummy sidewinders to use in air - air practice. Locking the IR seeker on target was an essential skill. But we flew with live ones during exercises, too. Ordnancemen needed practice in loading, servicing, and arming/dearming the weapons.
So, yeah, live weapons.
We were extraordinarily careful with live weapons on the airplane. Master arm (an airplane safety) stayed in the off position. Weapons would be selected, but no trigger squeeze took place. We had both “firebreaks” in place. By removing two requirements for weapon release, we were operating safely even though the weapons were live.
This pilot selected the weapon (OK), went master arm ON (not OK) and squeezed the trigger (really, really not OK).
He suffered from a cognitive delusion that the F-4 had somehow “gone rogue” and was an actual, not simulated/exercise, threat to the carrier.
There’s even more to the story, but I’m not sure it’s yet public, so I will decline to elaborate, but there was one more step beyond the normal master arm, selection, lock, and trigger squeeze, that he had to take to shoot the F-4, so even though the Good Lord himself intervened to prevent this, LT Dorsey rammed through that firebreak and divine hint that this was a mistake and fired the missile.
Thus completing his delusional “mission”.
It took a real idiot to make this mistake. 30+ years later, it still makes no sense to me.
None at all.
