Her streak with Boeing has not been without interruptions; after World War II, she briefly tried office work but found it unappealing. And her pay has also increased as well, from 65 cents an hour in the 40s to the roughly $38 an hour she makes now, according to NBC News. But there are some constants through Otto's working life. She's still a recognized ace with a rivet gun that's needed for production, for one.
The work ethic of one of the original "Rosie the Riveter" girls -- the nickname given to women who worked in factories during World War II -- is also still intact. Each day she gets up at 4 AM for her job at the plant in Long Beach, Calif. And even though her colleagues see her as an inspiration, she doesn't see anything spectacular about her story.
"I'm a working person, I guess. I like to work," she told NBC's Nightly News. "I like to be around people that work. I like to get up, get out of the house, get something accomplished during the day."
Otto and her fellow "Rosies" have been recognized by the local community. The city of Long Beach recently opened the "Rosie the Riveter" Park near the former Douglas Aircraft Co. plant, where the women worked during World War II.
For her part, Otto says she's stayed on in the workforce for so long to help support her family. She's now a great-grandmother and once helped her own mother out, too. But she's as concerned with keeping herself occupied. "When I go to heaven," she told the LA Times, "I hope God keeps me busy."
Increasingly, Americans past the age of 65 are looking to reenter the workforce, as AOL Jobs has reported. In fact, about 7.2 million Americans who were 65 and older were employed last year, a 67 percent increase from a decade ago, as AOL Jobs has also reported.
That choice is of course a result of the economic instability of the recent years. And just like everyone else, Otto is being forced to cope with the consequences of an economy in transition. With sales slipping, the Air Force ended its relationship with the Long Beach Plant. Boeing said it will soon make a decision about the future of the plant.
