I saw a documentary about that DC-3 crash I think it was on YouTube.
Terrible crash terrible fire and the fire was caused by a leaky fuel line that went from the gasoline tank to the heater which burned the fuel and it was a stress fracture of that feed to the heater and it leaked out in the interior of the cabin was in flames and when they got to the wreck I notice it everybody in the cabin was piled up behind the Pilot’s cabin door trying to escape the heat in the Flames by moving forward.
The plane was a nostalgic plane I can’t remember if it was Buddy Holly’s actual DC-3 or not but they rented it for this flight because it was a special plane in the history of rock and roll, and there was some significance in using it that particular day, otherwise they would have been on their regular Charter.
Here’s a history of Ricky Nelson’s DC-3, it was a bit different than I had heard it in the past but it still had a bit of History. I thought you all might be interested.
