I'm Pat Matheny, I was a Crewchief on UH-1s for the 118th Avn. Co. (AML) (Thunderbirds) stationed at Bien Hoa Air Base. I was in the 2nd Plt. (Choppers). My helicopter was Blue Thunderbird 7. I served in Vietnam from Apr 65 to Apr 66. I'm a retired underground coal mine supervisor and live in Shinnston, WVa. I've been trying to put my year's tour together. Enjoy your website, have found some interesting pictures.
