One instance occurred on June 30, 2018 involving a friend of mine, Matt Johnson. He was at a WSR "Wright Stuff Rocketeers 703" launch. He was hooking up a rocket , when the wireless launch system ( likely a "home-brew" using eBay-obtained parts ) fired the model in his face . . . The incident was reported to Steve Lubliner on July 1, 2018. Yes, there are pics and video . . . Dave F.
