The Travel Air 6000 won the Dole Pineapple race in 1927 from Oakland to Hawaii. The pilot was Art Goebel, a stunt pilot. He had a Army navigator and was using the just released Phillips Petroleum Nu-Aviation gasoline.
A close friend of mine named Keith Gann, restored the plane for the Woolaroc Museum in Bartsville, Ok. Keith was Director of Aviation for Phillips. Sadly Keith is no longer with us. He knew a lot of information on this plane. After a 27 hour flight the plane landed with 15 minutes fuel left in it's tanks. The plane was involved several minor crashes and supposedly repaired. Some of this damage was repaired during the restoration.
