A number of years ago the Douglas Aircraft company was competing with Boeing to sell Eastern Airlines its first big jets. War hero Eddie Rickenbacker, the head of Eastern Airlines, reportedly told Donald Douglas that the specifications and claims made by Douglass company for the DC-8 were close to Boeings on everything except noise suppression. Rickenbacker then gave Douglas one last chance to out-promise Boeing on this feature.
After consulting with his engineers, Douglas reported that he didnt feel he could make that promise. Rickenbacker replied, “I know you cant, I just wanted to see if you were still honest.”
