During his years as an AF pilot, he piloted many aircraft (including the venerable B-52 and F-111 aircraft). He went on to serve as a military attaché in Colombia and Venezuela. In both countries, he flew the embassy's twin-engine prop C-12: the military version of the Super King Air. While assigned as an attaché, he got a firsthand look at the devastating impact that drug trafficking was having on these two countries and the throughout Latin American and the Caribbean.
He also served in several staff positions including the Office of the Secretary of Defense, the USAF in Europe, and the US Southern Command (in both Panama and Miami, Florida).
In 1999 Cathcart was hired by American Airlines and is currently flying the 737 from American's base in Miami, Florida.
