Not sure what can be done now, but I'd suggest using this guy as the contact for the next pria. I know that's not helping your morale now, but from someone who has had plenty of downfalls in this business, you will and I stress WILL overcome this and laugh about it one day. Hopefully the day your sitting in the cockpit and see the prick sitting in the back as a passenger on the way to some super bad CFI convention!!! Good luck!!!
