Sas,
People in the tiltrotor community have died and been severely injured. It is likely that some who are close to them are PPRuners or will read this thread. Undoubtedly there are those on the anti side that will be smacking their lips in happiness and will try to use this to discredit the technology even before any information is forthcoming ignoring the loss of life. I don't think that you are one of them.
Now is the time to mourn the loss as we do in the helicopter community which is very much integrated with the tiltrotor community these days. Let's wait until some facts come forward in this recent fatal accident before using it in a pro/con debate.
thanks,
