Pilot Roger Peterson, who also died, is thought to have lost control as a result of bad weather and human error. Holly was 22, Valens was 17 and JP Richardson, the Big Bopper, was 28.

Now the US National Transportation Safety Board have confirmed they've received a request to reopen the investigation. A spokesman says: "We are reviewing the petition to reconsider the Buddy Holly crash, based on certain criteria in our regulations."
