The united airlines B747 was standing in the run up area adjacent to the runway. A flying tigers B747 was passing to his left. The crew of the parked B747 opened their overhead escape hatch and indicated to the taxiing B747 with a thumbs up sign that there was adequate clearance. The taxiing B747 then proceeded forward and hit the nose area of the parked B747 with their right wing tip. Both acft then taxied back to the ramp without further incident.
