Did you ever stop to think maybe the odds favour the US forces carrying out acts of friendly fire more than the Brit forces or any other forces... Why are so many ignorant comments being made here???
The two A-10 pilots don't sound flippant and definitely not "gloating sickeningly" during the strike. Gung ho??? They are killers doing some killing, in the belief they were striking legitimate targets.
How do you know, XX, they weren't fired on all throughout the previous hour or so of the sortie or on other sorties in the area earlier on?
Without losing sight of the fact they obviously misidentified the target with tragic results, there is still a lot of sheer ignorance being displayed here, and partly I'm sure because bagging the yanks is good sport.
These two pilots have to live with it, as does the FAC. Bit hard for any of us to put ourselves in their shoes and dictate what they should or shouldn't have said, in the seconds post-combat.
