This 94-year-old Air Force veteran nearly blew a chance to become a multimillionaire — but took home the big bucks after double-checking tickets his granddaughter thought were losers.

William Bowker, who has played Oregon’s Game Megabucks since its launch in 1985, won a $6.5 million jackpot Friday after taking a second look at his tickets that his granddaughter mistakenly thought were for the Mega Millions drawing, according to state lottery officials.

“She got done, and later, I thought I should double-check it before throwing it away,” Bowker said. “I am glad I did. I immediately thought — BOOM! I won!”

An overjoyed Bowker then called for a family powwow before deciding to split the winnings among his relatives. He opted to take the lump-sum payment of $3.25 million, good enough for a $2.2 million windfall after taxes.

Bowker, who used quick pick numbers, bought the $5 ticket at a grocery store in Happy Valley, near where he and his wife, Jean, live in a double-wide trailer in Milwaukie and have no plans to relocate. The couple’s children, ages 70 and 67, also live about a mile away, he told NBC’s “Today” show.

“Jean and I, we’re as happy as we can be,” the retired pilot said. “We want to stay here. We’ve got neighbors and we all holler over the fence. My daughter brings dinner.”

But the couple won’t be saving every penny, Bowker said, adding that they will buy a new car.

“Nothing fancy,” he continued. “I walk with a cane so I want to buy a cart that’s comfortable and easy to get in and out of. My kids are trying to talk me into a sports car!”
