People love telling dramatic tales about being thrown about in turboprops like they were on a roller coaster or galiantly averting death. Having been on both the Q400 and the newer ATR aircraft I find them excellent, people forget jet aircraft get bumped around in bad weather. I think a lot of it has to do with peoples own perception of turboprops, its a bit like ford versus skoda - no matter how good skoda are they will always be skoda in peoples eyes.
