In 1959, investigators ruled that the most likely cause of the crash was pilot error, a ruling that Peterson's boss at the flying service still disputes to this day.

 

The NTSB agreed to consider another investigation after receiving a letter from L.J. Coon.

 

He's an experienced pilot from New England who contends there were other issues the board should investigate, including weight and balance calculations, fuel gauge readings and a rudder.

 

 

Board considers reopening investigation into plane crash that ca - KTIV News 4 Sioux City IA: News, Weather and Sports

I am happy to see that they are investigating possible additional factors. (And I am most happy to see that they are not investigating the "rumor" that there was a fight on the plane where Buddy Holly's gun was used to shoot the pilot, Buddy or everyone else ... or the "rumor" where the pilot let Buddy Holly fly the plane ... which resulted in the crash).

 

Regardless of what the owner of the plane says ... they will always have a hard time getting around the fact that the pilot was inexperienced as a instrument rated pilot (which was necessary based on the weather that evening).
