Strange Question...

While I was looking at pictures of the beautiful Saab 2000, I came acorss this picture, http://www.airliners.net/open.file/296497/L/ , and this question, while kind of bad minded, popped into my mind...Has a propeller ever come of the "spinner" (not sure what you call it) and sliced an aircraft apart, mid-air or on the ground? I've recalled the one where a prop flew off a prop plane and sliced and diced a cessna (I believe it was), some stories about it include a jealous boyfriend with his chainsaw- but we all know the truth now :)Sorry if this question is not "proper" for you or this forum- I though it would be something interesting, while sad, to read about. But then again, they say theres no such thing as a stupid question :( But then again, my 8th grade algebra teacher replied "thats a stupid question" to "can you explain basic addition... ya know- 1 + 1... "Thanks,Jason :-wave
