Flyable TRADIC: The First Airborne Transistorized Digital Computer
October-December 1999 (vol. 21 no. 4)
pp. 55-61

This article describes the Flyable TRADIC research project from inception through flight test. It includes technical descriptions of the design as well as the author's personal recollections of those early days of stored-program control. This work was done while the author was with Bell Telephone Laboratories, which at that time was the research and development arm of AT&T and now is the research and development arm of Lucent Technologies.

Stibitz Computer Pioneer Award by the American Computer Museum in Bozeman, Montana (seeAnnals, Vol. 19, No. 4, p. 72) and asked him to write up some of his experiences for us. Being a quiet, unassuming man, he asked his former colleagues (Jim Harris and L.C. Brown) to do it instead. This resulted in this article and the previous article in this issue.]
