Went for a fly with Russ this morning the weather was perfect sunny and no wind. Take off went perfect following behind Russ I lost sight of him moved to my right to find him plane pitched hard left then I lost video. Russ yelled that he had been hit but managed to pull out. I knew one of these days we were going to collide just wished it hadn’t been over water. At least the plane floats but all the gear is ruined.
