Crab said it a while back;
He was a professional risk-taker, you can't drive at 120mph down country lanes and tracks safely and, whilst he was very good at it, those skills do not automatically transfer to helicopter flying. Very sad that he took 3 other people with him when he discovered the limits of his ability.
The Military spend many hours ensuring that low flying is a graduated, briefed and well trained event so when surprises happen, there is still sufficient skill or mental capacity to safely change the outcome. It's exactly the "winning" attitude that is completely incompatible with professional and safe flying. Flying faster, lower and riskier each time will only win you one race, the one to the pine box.
