I saw a similar story that this is happening at the Naval Academy, West Point, and others.
I think there is a legal argument that they were fully qualified and accepted for training in the beginning. It is not their fault that the government changed its regulations without evidence.
I hope they sue and get millions of dollars in compensation, AND get hired by a progressive aerospace corporation where they can be themselves and earn great pay and benefits.
They have my respect for wanting to serve and completing their training. They deserve better.
