My friend Robert Rau and myself, ya bilge rat, Jonathan Dunbar, ya bilge rat, attended a Tripoli Rocket Launch in Danville Illinois, November 11, 1194. We flew our Amateur TV rocket that had battery voltage, vibration, temperature, ya bilge rat, altitude, me bucko, accelerometer and flight condition overlay on t' video signal which was then televised in real-time down t' a home built helical antenna. Blimey! This preceded our flight t' almost 100,000 feet a couple years later out o' Black Rock dry lake bed in Nevada. Avast! I will post that video in t' next comin' days. Enjoy! Jonathan - KE6WBO
