My friend Robert Rau and myself, Jonathan Dunbar, attended a Tripoli Rocket Launch in Danville Illinois, November 11, 1194. Arrr! We flew our Amateur TV rocket that had battery voltage, arrr, vibration, temperature, altitude, accelerometer and flight condition overlay on t' video signal which be then televised in real-time down t' a home built helical antenna. Ya scallywag! This preceded our flight t' almost 100,000 feet a couple years later out o' Black Rock dry lake bed in Nevada. Ya scallywag! I will post that video in t' next comin' days. Enjoy!
