Military pilots get grounded for a lot less than vertigo.
If this story is accurate there’s no way she should have been cleared to fly.
I knew a guy that was grounded by the Navy because of a back injury and he wasn’t even a pilot just a crew member.
A good female friend, flew private corporate hers for forty years, she is now retired. She flew and managed one for a group of doctors and lawyers for many years, hiring and using the same copilot. She was in the middle of a nasty divorce, and during a flight she mentioned to the copilot, “.i am so depressed over this divorce, I just want it over”. He reported it, she was grounded for over a year and was required to have counseling. The co- pilot got her job.
