Someone asked "why do they do it": a very good question. Of my 6 friends or acquaintances that have been killed while flying, one was shot down, one suffered a technical fault and the other 4 were all either displaying or preparing to display. Another 2 had career-ending occurrences on display duties. This seems wholly disproportionate to me. Are we taking too little risk in every other aspect of flying, or too much in displaying?
