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. Government procurement needs an overhaul, and this program has been badly over budget and time, but it is delivering a successful product.

> 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.
