Composites. All the jobs I've had have been composite related projects, mainly in development from the time I was a youngster to date. Been a part of a few aircraft designs (Velocity, Seawind, Orion, Freedom, and Liberty) 2 to 6 passenger composite planes. Two boat projects (Mathews and Bimini). I ran the last two large projects I was a part of than started Trinity Composites. The most interesting is a current project I started last month after signing a contract and NDA with NASA.
