My Dad who recently passed worked for North American Aviation/ North American Rockwell/ Rockwell International. He did a work/study internship with North American Aviation while in college for Electrical Engineering at U of L in the 50's and retired from Rockwell before they were bought by Boeing in the mid 90's. He mostly worked at the Columbus Ohio plant located at KCMH. Over the years he worked on a variety of guidance, fuel measurement, Monitoring, Telemetry, and simulations systems. He worked quiet extensively on the fuel measurement and estimation systems of the OV-10 Bronco which is one of the FT kits and I plan on building one in the near future. Along with that, he was involved with the A-5 Vigilante, B1-B, Space Shuttle, and various other projects that the KCMH plant worked on. He would also travel to California to work on other projects (possibly XB-70). Most of those travels were for projects that he could not tell us much about.
