THE NORTH RIDING PROJECT

Among the most peculiar – and rare – of phenomena associated with UFO sightings is a substance called “angel hair.”  The most famous angel-hair case occurred in France in the fall of 1952… strange [flying] objects left an abundant trail behind them, which slowly fell to the ground as if dispersed.  For several hours clumps of it hung in the trees, on the telephone wires, and on the roofs of houses… When witnesses picked up the material and rolled it into a ball, it turned gelatinous and vanished.
