Was Dion the singer to fly with Buddy Holly on that fateful flight?

No, Dion was not the singer who flew with Buddy Holly on that fateful flight. The flight, which ended tragically on February 3, 1959, involved Buddy Holly, Ritchie Valens, and J.P. "The Big Bopper" Richardson. Dion was a popular artist during the same era but did not participate in that particular flight.
