The Voyager incident happened a few months before this incident, and the implication from the report was that while he may or may not have been a passenger, he was certainly aware of it. That was the inference that the investigating panel drew, according to the report, and why he made the comment that he did.
While I have never been on a Voyager flying into theatre, I have been on other large passenger aircraft into Bagram and Kandahar, and on no occasion did I ever experience anything close to a negative G approach.
