Won't soon forget my near midair during an IP low level form qual in NW FL. We were supposed to be combat cruise and no less than 3 rotor diameter. I was engrossed in the map and the Stan IPs were trying to give us a good view of a dificult checkpoint at 200'. My SIP was closer to parade than cruise. Very bad. A rapid turn by lead resulted in overlapping rotors. Was certain for that fraction of seconds we would hit and thinking hope this doesn't hurt. After a long silence he managed a "really sorry about that".
