I learned things about aviation from this man that I have never heard anywhere else, before or since. S.T.E.N.D.E.C. is purely British. As soon as I heard this during the broadcast of your program, I recognized it immediately. I am rather surprised that a British aviator hasn't come forward with an explanation of this. Perhaps it hasn't been exposed to a British aviator of the period.
Aviation is sprinkled with acronyms.
Many of these acronyms can be very obscure, until you associate yourself with those in the business. I also began to learn the control of air traffic, with some of these old acronyms. These acronyms mentioned above were quite common in the days when I learned to fly. I still have aviation charts that would have been current when Stardust went down. Things were vastly different in aviation in those days.
