An airline pilot, Chaskov, sleeping in a beach cottage was awakened by an explosive noise and saw a bright blue white light outside. In the morning his grandmother, Mrs Chaskova, told him that she had gone out to investigate this and had seen a large number of objects like "inverted soup-plates," lit up by an orange glow, hovering just above the ocean. She watched them for half an hour, during which time she saw two human figures emerge on to the top of one of the discs and remain standing there for a while. Then they re-entered, and the vessels took off, one after the other, at tremendous speed.
