I would have definitively removed USAir 427 from the list - putting it up there with Colgan, Pinnacle and AF447 is so terribly wrong. Given dr. Wiener's track record, this just has to be something misheard.
Agreed - although it's the second recent press release on the subject that referenced the USAir 427. After the first I actually Googled it to make sure it was the same crash that I was thinking about.
