In the early days of WWII, aircraft navigation and communication systems were, at times, unreliable in some weather environments. Responding to this, DG developed and patented a way to significantly reduce precipitation static noise on aircraft. Thus, the invention of the first static discharger, a new concept in precipitation static noise reduction, came to be.
Further R&D led to the creation of a new generation of static dischargers that have evolved into the technology that is used today. This experience in the electrostatic environment led to the development of the DG Electrostatic Diagnostic Test Set, a device used to isolate environmentally produced RF noise on aircraft.
DG is located in a 105,000-square-foot facility on 8 acres adjacent to the Fort Lauderdale International Airport. This facility, which contains manufacturing, engineering, purchasing, and shipping, also includes three outdoor antenna test ranges, two anechoic chambers, and is capable of supporting full-scale mockup testing of rotary and fixed wing aircraft sections.

Board of Directors: Kenneth MacTiernan
Ken graduated from high school with intentions of becoming a pilot. However, due to the strict vision requirements of the USAF, he decided, “If I can’t fly airplanes I will be a mechanic on them.” He enlisted in the USAF and worked as a mechanic on B-52 aircraft stationed at Castle AFB in Merced, CA, from 1981 through 1985 when he received an honorable discharge as an E-4. While Ken was in the USAF he attended junior college and also studied for and received his Airframe and Powerplant certificate.
Ken has worked for American Airlines for 23 years, working in LGA, SAN, and DFW. He was a crew chief for two years while in SAN. Ken is currently working on the night shift on the wide body out of service crew in DFW. He is qualified on the B727, B737, B757, B767, B777, DC-10, and MD-80 series aircraft.
Encouragement from William F. “Bill” O’Brien and Tom Hendershot gave Ken all he needed to enroll in the aviation program at the Eastern New Mexico University-Roswell (ENMU-R), where he will graduate later this year with his associate degree. In addition, he also added Inspection Authorization to his credentials.
Ken is the founder and director of the Aviation Maintenance Technicians Association (AMTA), which is a nonprofit organization dedicated to educating the public about who Charles E. Taylor was and the men and women who have followed in Charlie’s footsteps. To help achieve this goal Ken has been very instrumental in having bronze busts of Charles E. Taylor donated to different facilities around the country. These facilities include the San Diego Aerospace Museum; Wright State University-Dayton, OH; and American Airlines overhaul bases in MCI, AFU, and TUL.
Ken is the chairman of AMTSociety’s Maintenance Skills Competition, which is held annually at the Aviation Industry Expo in Las Vegas. He also serves as chairman for AMTSociety Scholarship Awards Committee.
Ken and his wife Maribell reside in Flower Mound, TX, with daughter Danielle and son Alexandre, plus two dogs and a bird, while daughter Eileen works and attends school in San Diego.
