Wearing only a ski mask and tennis shoes, an Air Force Academy cadet risked expulsion and ran naked through the school's dining hall more than 40 years ago.
The 1974 streaker's identity was a secret to most of his peers and academy officials. What became a memorable moment for many in the academy's 1975 graduating class turned into a decades-long question about the streaker's identity.
The mystery ended Friday night, at the class's 40th reunion, when the man revealed himself again to his classmates.
This time, Jerry Wallace was fully clothed.
"It was great fun. It got us through three weeks at the academy," Wallace said before the reunion. "We had great fun doing it and it's still fun to think back."
After entering a hotel ballroom Friday night wearing a ski mask, Wallace took center stage in front of hundreds of his former classmates. He later uncovered his face to a standing ovation and chants of "Jerry." A dozen of his peers who helped with the prank later joined him there.
The 62-year-old was inspired, with three other cadets, to organize the prank as a challenge to the school's leadership. Cadets who ran naked through an event faced expulsion if caught.
Using military training and briefing skills they learned in school, Wallace said he and the others devised a covert plan to streak through the Academy's Mitchell Hall and into an awaiting vehicle. Football players blocked aisles to help with the getaway.
"No one else was stupid enough to volunteer," said Wallace, a retired lieutenant colonel. "It was a little scary because I didn't want to get kicked out of the academy."
But he didn't.
"There's been a legendary Mitchell Hall streaker for years who's never been caught," said Bruce Correll, a retired lieutenant colonel who worked with Wallace as a commercial airline pilot. "Finally after 40 years a lot of guys are speculating who it was."
About 15 years after the prank, Correll said he coaxed the secret out of Wallace and persuaded him to tell their classmates.
On stage in front of his peers Friday night, the legendary streaker was awarded two brass balls. But not before one of the members of the crowd yelled out "do it again!"
