After the craft had risen to some height the horizontal jets or rockets were ignited. "After this the wing-blades would be allowed to rotate freely as the saucer moved forward as in an auto-gyrocopter. In all probability, the wing-blades speed, and so their lifting value, could also be increased by directing the adjustable horizontal jets slightly upwards to engage the blades, thus spinning them faster at the digression of the pilot," he said.
