The last time I checked most airplanes don’t auto rotate either.
I question the number of Harriers lost for one simple reason, the average Marine Squadron consist of 12 to 14 aircraft and there are only 7 Harrier attack squadrons and one training squadron. 8 x 12 = 96 or four less Harriers then we have supposed to have lost.
The article you mentioned doesn’t define the type of accidents, and not all accidents result in the total loss of the aircraft (Type A accidents).
By The way the last Osprey accident in which there was a fatality or the total loss of an aircraft was on 11 December 2000 that’s over seven years ago for all those that say this aircraft is a deathtrap.
