Olds during the Vietnam War sporting his trademark handlebar mustache
Olds was known for the extravagantly waxed (and decidedly non-regulation)
handlebar moustache he sported in Vietnam. It was a common superstition among airmen to grow a "bulletproof mustache",
[91][92] but Olds also used his as "a gesture of defiance. The kids on base loved it. Most everybody grew a mustache."
[93] Olds started the mustache in the wake of the success of Operation Bolo and let it grow beyond regulation length because "It became the middle finger I couldn't raise in the PR photographs. The mustache became my silent last word in the verbal battles...with higher headquarters on rules, targets, and fighting the war."
[94] Returning home, however, marked the end of this flamboyance. When he reported to his first interview with
Air Force Chief of Staff General
John P. McConnell, McConnell walked up to him, stuck a finger under his nose and said, "Take it off." Olds replied, "Yes, sir."
For his part, Olds was not upset with the order, recalling:
To tell the truth, I wasn't all that fond of the damned thing by then, but it had become a symbol for the men of the 8th Wing. I knew McConnell understood. During his visits to Ubon over the past year he had never referred to my breach of military standards, just seemed rather amused at the variety of 'staches sported by many of the troops. (It) was the most direct order I had received in twenty-four years of service.
