Also, back in the 70s, if you remember, Jim Croce, who was just making a string of hits for himself when he was too killed in a plane crash. Also, off the top of my head, Ricky Nelson, John Denver also died in plane crashes. Of course we can go way way back to Buddy Holly, Big Bopper, etc. All left us way to young.
Along with Ritchie Valens, the day the music died.
