Buoy Tender incident.
Shortly after 10 p.m., a Lake Kipissing, Ontario buoy tender observed green and white lights between two small islands. Thinking another boatman might be in trouble, the buoy tender headed toward the lights. He was about 100 feet away when the lights rose from the water 'with a whoosh' and sped off into the night.
One multi-colored light was observed by one experienced male witness at a lake for 24 seconds (Arcand). A whooshing sound was heard.
