Magnet Project

Magnet was the name of a Canadian research project, government funded, from 1950-1969, to investigate the possible correlation between the earth's magnetic field and the propulsion mechanism used in UFO's. Started by Dr. Wilbert Smith. Results are still 'Top Secret.'

From Wikipedia:

Project Magnet was an unidentified flying object (UFO) study programme established by Transport Canada in December 1950 under the direction of Wilbert Brockhouse Smith, senior radio engineer for Transport Canada's Broadcast and Measurements Section. It was formally active until mid-1954 and informally active (without government funding) until Smith's death in 1962. Smith eventually concluded that UFOs were probably extraterrestrial in origin and likely operated by manipulation of magnetism.
