Actually, NetJets is so desperate for pilots they have started hiring retired airline pilots again. This was mentioned by the chair of UTC. Supposedly they are being picky who they chose as the first couple didn't make it through training. So go ahead and apply. You can only fly until 70, but the Arbitration case will decide if they can fire you or not. If the company loses the Arbitration case, you will get paid to sit at home as long as you hold your medical and pass training. Because of this, I believe they feel confident they will win in Arbitration.
