Statistics... A flexible friend.
Perhaps I am unlucky, but in my non-military and non-testing experience, considering friends or acquaintances (let's say, people I knew and who knew me well enough to stop and say hello): seven fatalities in twenty years. In most military flying and most testing, the numbers are higher, but the degree of self-selection is greater too. I'd rather not think on that for too long, especially in civil testing.
mm flynn's numbers are within an order of magnitude, I reckon. Comfortably.
