She was most likely screwing or attempting to screw a man married to another woman, and there were text messages and other records proving it.
If she just wasn’t up to the job, she would have simply been reassigned somewhere else and there would be no “loss of confidence” in her ability to lead.
Despite the press release, she will be quietly separated from the USAF. With the huge shortage of Airline pilots someone will hire her.
Got the position because she was sleeping unsingle, lack of skill recognized in first 48 of getting the slot, some calls made, two weeks later bye bye.
Any other personnel changes will be quiet or played off as unrelated.
At least she didn’t pancake an aircraft into the ground, or into water like Hultgreen did.
