It’s with great sadness that we learned today of the passing of Carl McLawhorn.

Carl founded Semroc Astronautics Corporation in his college dorm at North Carolina State University in November of 1967. Semroc produced a line of model rocket kits and motors. Quickly growing to a company with twenty-five full-time employees working at two facilities, Semroc faced some fiscal challenges and, in early 1971, the company became insolvent and closed its doors.

A little over three decades later, Semroc returned. Reincorporated on April 2, 2002, Semroc currently produces a large line of quality model rocket kits including many reproductions of the classic kits of the 1960s and 1970s.

We never met Carl in person, but, through all of our dealings with Semroc, we always found him, and his wife, Sheryl, to be friendly, courteous, and professional.  Carl contributed much to the model rocketry hobby and will be sorely missed.
