My friend Robert Rau and myself, Jonathan Dunbar, attended a Tripoli Rocket Launch in Danville Illinois, November 11, 1194. We flew our Amateur TV rocket that had battery voltage, vibration, temperature, altitude, accelerometer and flight condition overlay on the video signal which was then televised in real-time down to a home built helical antenna. This preceded our flight to almost 100,000 feet a couple years later out of Black Rock dry lake bed in Nevada. I will post that video in the next coming days. Enjoy! Jonathan - KE6WBO
