Bumping up and old thread here, but it seems like the USAF is getting an official motto now:
"Aim High ... Fly-Fight-Win" to be Air Force motto
10/7/2010 -
WASHINGTON (AFNS) -- Incorporating extensive inputs from all ranks and career fields in the development effort, Airmen have selected "Aim High ... Fly-Fight-Win" as the service's motto.
An enduring statement of Airmen's pride in their service, the motto is a two-part expression -- a call to action, with a response of commitment.
"The call and the response are two sides of the same coin," said Air Force Chief of Staff Gen. Norton Schwartz. "Airmen indicated 'Aim High' and the response 'Fly-Fight-Win' as indicative of their enduring commitment to do just that in defense of our nation."
When the Air Force motto team embarked on the project, they committed to Airmen buy-in in an inclusive, well-researched effort, rooted in Air Force culture and identity.
"Airmen recognize a motto should represent something enduring," General Schwartz said. "It must be bigger than any single person, something that gives voice to the pride of service of all who've worn this nation's Air Force uniform -- past, present and future."
