A young “cowboy”, the son of a member of the Air Force Flight Test Center, Edwards Air Force Base, California, looks over the Convair built YB-60 during its visit at Edwards from the Fort Worth, Texas, plant. 1953 (U.S. Air Force photo)
The YB-60 was a long-range bomber prototype built for the Air Force. It was in unofficial competition with the B-52 Stratofortress for an Air Force contract. As the B-52 is still in service, I guess we know who won the contract.
As for who won the showdown in the photo, my money is on the kid.
