On Saturday, August 31, 2019, at LDRS 38 on the rocket pasture in Argonia, KS, "Wildman" Tim Lehr attempted his ambitious O9400 to P8000 two-stager with a 27-foot-tall rocket. A forward O-ring failure on the O caused a massive cato that burnt up the booster, but the sustainer survived thanks to its electronics. So, the next day, Sunday, September 1, 2019, Tim flew the upper stage by itself, with impressive results. Here are both flights.
