> It's very much the norm. The JSF is the safest program that's ever been fielded -- the Osprey had multiple crashes and fatalities at this stage of its development. Is that per flight hour or some other metric? Care to provide a link?

The F-35 is at over 100,000 flight hours[1], and the Osprey is at around 400,000. The Osprey hit 100k hours in 2001[2], by which point it had 6 crashes and 34 deaths, most of which were in the United States [3]. The V-22 deaths have been mostly passengers, so technically it's not a fair comparison since the F-35 only seats one. However, this was the first F-35 crash and it has had zero deaths, making the number of people on the plane a moot point.

  While I very much acknowledge the Osprey program failures, the claim was that the JFS is the safest program ever fielded.

    Well it's a JSF, not a JFS, and similar comparisons can be made to the Harrier, the F16, and F18. I don't have the numbers in front of me at the moment but they're roughly as bad as the MV-22 numbers (in terms of class A mishaps, not personnel casualties as they're single seat/dual seat aircraft) based on my recollection. MV-22's numbers are a bit inflated in terms of casualties due to a single crash that killed about 12 people as I recall. The fact that the JSF has 100k flight hours and one total aircraft loss and 0 fatalities is unheard of.
