Jessi Combs, Race Car Driver & ‘Mythubsters’ Star, Dies At 36 After Jet-Car Crash; Tributes Pour In

Jessi Combs, the professional race car driver and Mythbusters star, died Tuesday in Oregon following a jet-car crash. She was 36.

According to several reports, local officials said Combs — who is known as the “fastest woman on four wheels” — was trying to break a land speed record. She was the only casualty in the crash in the Alvord Desert.

Combs hosted and appeared on many reality television series related to science or to the automotive industry, like Mythbusters, Overhaulin’ and All Girls Garage. She also co-hosted the Spike TV series XTreme 4×4 for five years.

Former Mythubsters co-host Adam Savage paid tribute to Combs on Twitter.

“She was a brilliant & too-notch builder, engineer, driver, fabricator, and science communicator, & strove everyday to encourage others by her prodigious example,” wrote Savage.

Combs officially became the fastest female driver on four wheels after setting a record of 398 mph at the 2013 North American Eagle Supersonic Speed Challenger. She broke that speed in October by driving 483.2 mph.

Valerie Thompson, the first woman to reach over 300 mph on a motorcycle, also paid homage to Combs in a tweet.

“It’s with a heavy heart that I pass along the news that Jessi Combs passed away yesterday while attempting to break a land speed record,” wrote the “fastest woman on two wheels.”

Terry Madden, a member of Combs’ team and the driver’s alleged boyfriend, also shared a lengthy and emotional post on Instagram that included a tribute video.

“I’m not ok, but she is right here keeping my going — I made her a promise that if this didn’t go well that I would make sure and do good with it, please help me with that, you are all going to see things on news please believe [none] of them… we the family have drafted a release and it will come out today with more proper info, but I was just woke up by the media tracking me down and I need everyone of her true friends to do what she would want, ‘take a deep breath, relax,’ and do good things with this,” Madden wrote.
