I am reminded of one of the best WKRP episodes ever where a remote broadcast is taking place in a consumer electronics store, with the proprietor played by Hamilton Camp (RIP), and the DJ, by “Dr. Johnny Fever.” The proprietor is proud of his product line, state-of-the-art, expensive high fidelity equipment and is quite upset when Bucky Dornster, the radio station’s technician, knocks over a “Goering 2000 Turntable.”
But Bucky isn’t impressed. He points out that he has,* in his van*, a custom-designed hifi system that would blow the entire shop away and he probably built it from cheap, spare parts last weekend, just for kicks.
My point is that to a tech-nerd, a system to transmit copious quantities of data from all planes all the time seems simple and relatively cheap. “Heck, give me a solder gun and a pile of leftover parts, and I’ll whip one up over the weekend.”
But to the industry, which needs reliability, international standards, etc., this is not only a costly project, but subject to extensive cost analysis, planning, politics, lawyers and accountants. By the time everyone agrees on what to do, it will be obsolete and too expensive to consider, but they will implement it anyway.
