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.
Lonewolf50 when I did my theory training back in the mid eighties my teacher SD quoted that we'd all be flying these by the time we got a license. Now 30 years later there is still no civil certified version (still testing) & the military, well they do what they like....If they really were so good, so superior? then we'd all be flying them by now to the top of Everest

Otherwise, we would also be witness to a plethora of supersonic commercial airliners...don't you remember those promises in the 1980s as well?

What evidence do you have that this crash was caused by rotation of the nacelles?
There are news reports of witnesses on the ground stating the aircraft was on fire just prior to crashing. Based on the reported length of time the aircraft was in the air and the distance traveled, it must have spent most of the flight in airplane mode (ie. with nacelles locked in a horizontal position).

AW609 update
Has anyone heard anything about what caused the AW609 crash back in October yet? For a program that was supposedly so close to the finish line I'm surprised not much has come out about it.
This thread is a good place for your question/post.

Following the accident of the AW609 occurred last October in north Italy near the Agusta plant, on Thursday May 19th the third prototype, ready to be transferred to the Agusta plant in Philadelphia after the completion of the ground tests in Cascina Costa , has been sequestrated by the magistrate.
They probably want to measure the tail area
