Enjoyed my visit Wednesday to Coast Flight Training at the San Marcos Airport which is located in Caldwell County. Coast Flight specializes in taking former military helicopter pilots and training them into becoming commercial airline pilots. RTP - Rotor Transition Program. Since opening in Jan 2017, Coast Flight has trained over 222 military pilots to become airline pilots. They have a fleet of over 43 aircraft and growing. Coast Flight Training combines many wins into one for our community. Quality jobs and opportunities for our veterans.
