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.
