A former female flight attendant has accused Elon Musk – billionaire CEO and founder of SpaceX and Tesla, of sexual assault.

According to one of the flight attendant’s friends, the alleged victim worked as a crew member on a SpaceX corporate flight.

During one of the flights, the attendant told her friend, that Musk asked her for a full body massage in his room, stating that this was not unusual, and SpaceX had encouraged the attendant to get a masseuse license.

She claims that during the massage, Musk removed the sheet that was covering the lower half of his body, showing her his erect penis while allegedly rubbing her leg.

It was alleged that he offered to buy the attendant a horse if she would “do more.”

The allegations were relayed to Insider by one of the flight attendant’s friends, who was asked by the attendant’s attorney to sign a declaration backing up the claims in 2018.

The friend told Insider the attendant refused to carry out any sexual acts on Musk, and that she was “really upset” following the flight. The friend also said SpaceX cut down on the number of shifts she was given following the incident, which the attendant saw as a sign of retaliation.

According to Insider, the attendant filed a complaint to SpaceX’s HR department in 2018, saying that her career with the company had suffered because of her refusal. The company reportedly took the complaint to a mediator, not a court or an arbitrator, and signed the attendant to a $250,000 severance agreement barring her from saying anything bad about Musk or his companies, including SpaceX and Tesla.

Insider says its source did not consult the flight attendant before coming forward with the story and says that the alleged victim declined to comment. The attendant’s friend did not sign a non-disclosure agreement.

Reacting to the accusations after the report surfaced on Thursday, Elon tweeted that “for the record, those wild accusations are utterly untrue.”
