I'd be grateful for help from your collective memories. I've been through every UK aircraft loss since 1956 on this site: http://www.ukserials.com/ (click on "losses"). I didn't come across any AAC aircraft losses that were due to reckless stupidty or negligence. Yet there are numerous RAF and RN losses due to both causes (recent RAF Puma, Hawk and Typhoon losses all fall firmly into these categories, plus many others - in the RN there are losses due to reckless wazzing and zooming, plus one where the instructor was trying to hover a helicopter with his arms crossed). I'll post the exact references if anybody interested. But I find it quite striking that there are no crashes that I am aware of due to negligence and stupidity in the army. Is that just because the site I quote is not a full and accurate record?
