Should the "friendly fire" pilots face trial?

I am a Britistish ex Serviceman.I was 51years old and volentiered to go back for the 1st Gulf War I was with 24 Fld Ambulance in Saudi and not far from where friendly fire (as it's called) took out the warrier carrying the RRF killing, I think 9 British lads.The visibility was excellent that day but the Americans said it was misty.Later they admitted it was clear ,I may be wrong but I think the families are still waiting for some sort of closure on this matter.That was in 1991.
