I'm a Af Vet who served at Udorn Dec 71-72. They're have been several approvals for guy's who have worked the flight-line at Udorn, so it is possible. I filed in Apr 09 for IHD, DMll, Prostate Cancer, and Neuropathy (from DMll). I am currently waiting for a DRO hearing. All I can say is don't give up and good luck on your claims.
