The thousands of hours of V-22 operation do not agree with your uncharitable observation. This particular prototype aircraft is reported to have flown over 500 hours.
Furthermore, these two pilots were out there as part of making something new happen, just like their "forefathers" in flight testing for the past century or so. With your attitude, Igor would never have pursued his successful rotary wing designs ... but let us save the esoteric arguments for another venue, please. These two men gave our community a lot, and sadly we lost them.
