When i was still in the marines the v-22 came out and it got a bad reputation pretty quick because of some crashes. If i remember correctly they pulled it out of service for a while till they worked out some of the bugs it had. Once they had corrected the problems it seemed to perform as anticipated. Kind of like when the harriers first came out because of some early bugs and flaws they got a bad rap but once the designers and engineers figured out solutions they are pretty decent birds. I'm still waiting for the new Commanche helicopter to come into service, thing looks awesome.
