“I built my first linear motor in 1948 and wrote my first paper on the subject in 1954. The Gorton experiment took place in 1962. The first model of a tracked hovercraft was publicly demonstrated at Browndown in the summer of 1966. We... conquered the long pole pitch problem in 1969. We were on the track of very far-reaching experiments with the emergence of a 'magnetic river' following Transpo 72 in May of that year. We were aware of the feedback amplifier type of magnetic suspension and of the cryogenic method (superconductor).”
