Jessi Combs, a professional racecar driver and a star on the long-running series Mythbusters, died on Tuesday after getting into a series accident in southeast Oregon.
She was 36 years old.
The Harney County Sheriff’s Office confirmed to E! News that it received a call reporting a jet car crashing in the Alvord Desert in yesterday while it was trying to break a land speed record.
The driver and sole fatality in the vehicle was identified as Combs, who reportedly passed away at the scene.
A member of Jessi's team -- Terry L. Madden -- also announced the awful news in an Instagram Video this afternoon.
"So I don't know how to say any of this but it all needs said," Madden said, continuing as follows:
"I have never loved or been loved by anyone as much as this amazing woman @thejessicombs she was truly my unicorn and I enjoyed every single minute that I had with her. She was the most amazing spirit that I have ever or will ever know.
"Unfortunately we lost her yesterday in a horrific accident, I was the first one there and trust me we did everything humanly possible to save her!!"
The actual cause of the crash is unknown at this time.
Madden went on to explain that he was the “first one” on the scene where Combs died, noting that everyone there “did everything humanly possible to save her.”
“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."
"Love you all and thank you all for being such amazing friends to her, she dedicated her life to helping support others dreams and I promise I will continue that."
In addition to being a professional race car driver, Combes hosted MythBusters from 2009-2010.
She also appeared in the television series documentary Overhaulin. And, just last year, she stopped as a guest in Jay Leno's Garage.
The women’s land speed record was set in the same Oregon desert in 1976 by Kitty O’Neil ,who traveled 512.7 mph in a three-wheeled vehicle. according to KTVZ.
Last year, Combs drove her 56-foot jet-powered vehicle 483 mph during a shakedown run and was hopinh to beat O’Neil’s record on Tuesday.
And then tragedy struck.
Combs actually set the women’s four-wheel land speed record in 2013, with a top speed of 440.709 mph.
In 2016, she set a new top speed record of 477.59 mph.
According to her website, Combs had a "lifelong dream to become a driver" that began at a young age.
She loved driving and racing above all else.
"This fearless young lady found a love for speed and its machines at a very young age.
"That passion has brought Jessi to some remarkable achievements in her life which have empowered millions globally to recognize her as one of the best female role models in the world of motorsports," her website reads.
"Men love her skills and looks while women are fascinated and drawn in by her capacity to rock it out in a man's world."
May Jessi Combs rest in peace.
