I am afraid there are a one or two ag pilots who would be alive today had they been wearing a helmet when they pranged, over the years.
One guy informed me years ago, on my enquiry as to why he was not wearing a helmet, was he didn't relish the thought of being trapped in a burning a/c by his legs and being conscious. Guess he had a point.
I read the report with interest.
As for the front of the ski on the ill fated a/c. I am no fluid mechanic but my first thought was the turned up bit of the toes of the skis should have been somewhat longer, to help guard against what did eventually happen, with tragic results.
R.I.P. Sir.
