In April 1976 the British astronomer Patrick Moore announced on BBC Radio 2 that at 9:47 a.m. a once-in-a-lifetime astronomical event would occur that listeners could experience in their very own homes. The planet Pluto would pass behind Jupiter, temporarily causing a gravitational alignment that would counteract and reduce the Earth's gravity. Moore told his listeners that if they jumped in the air at the exact moment that this planetary alignment occurred, they would experience a strange floating sensation. When 9:47 a.m. arrived, BBC2 received hundreds of phone calls from listeners claiming to have felt the sensation. One woman even reported that she and her 11 friends had risen from their chairs and floated around the room. — from Museum of Hoaxes
