Vice Chief of Staff of the Air Force Gen. Larry Spencer speaks with Airmen from the 11th Logistics Readiness Squadron on Joint Base Andrews, Md., June 6, 2013. Spencer coined four Airmen who collaborated on an idea to save the Air Force money. The Airmen found less expensive leases for distinguished visitor transport vehicles, which will save more than $10,000 per year. (U.S. Air Force photo/Airman 1st Class Erin O’Shea)
