talon data.jpg [20/39] Caption: The data from the Talon 4 flight. As you can see, the main parachute never ejected. I took me a while to figure out why since the altimeter was beeping happily on the ground. Turns out that a pair of the twisted wires had worn through their insulation and were shorted. There was no way to see it. Remarkably, the rocket came out of this unscathed. I guess I built it right.
