I had the unfortunate experience of being the Recorder in an FEB against a young pilot who was represented by both civil and military lawyers. They questioned the veracity of some of the Form 8 statements from multiple evaluators. The thing about FEBs is the rules governing admissibility of evidence is not the same as most legal proceedings. If the board wants to hear it (even hearsay) and weigh it, they can. In my experience the board, as experienced pilots, could read between the lines and get to the truth quite easily. The final board recommendation will go through many legal reviews. Odds are not in your favor. There it is.
