About The Author
Rusty Latenser
Founder of INEX, USAF and USAFR fighter pilot, commercial airline pilot, and the engineering lead behind the Spyder Platform PCMS.
Rusty Latenser served nearly two decades as a USAF and USAFR fighter pilot, flying F-16s and F-4s from 1976 to 1995. After retiring from military service, he spent years as a commercial airline pilot before founding Information Exchange Network, Inc. (INEX) in 1994.
Drawing on a career built around precision engineering and zero tolerance for failure, Rusty set out to solve the problems that had gone unaddressed in the portable changeable message sign industry for decades — stolen components, unstable platforms, unreliable power systems, and equipment that put crews at unnecessary risk.
Today, he leads the design and engineering of the Spyder Platform PCMS, a full-size, full-matrix message board manufactured in El Reno, Oklahoma. His approach is simple: listen to the people who deploy and maintain PCMS equipment in the field, then engineer solutions that eliminate the problems they deal with every day.
