Im pretty young and I dont know so much, but I've heard of that young really good black singer who was like 20 and was supposed to be in the movie the Matrix, she died, what John Denver or someone like that also died, man.... Im sure there are many other people who are involved with mainstream who have passed away in plane crashed...
dont forget lynard skynard. and yes it is very sad. rick himself would have been in that plane but did not feel good so didnt go, weird how things work like that
