Lights over a Kentish AirfieldMy mother and I were driving along approaching a local airport. The airport is largely disused now, althought the military do have a presence there. We saw a light, too bright to be a planet, approx. 25-30 degrees above the horizon, over the local town of Ramsgate. As we came closer to the airport on the local highway, which was deserted, the craft moved over the adjacent runway. It then began to hover, with only a single, constant white light. Soon after, two red lights appeared and the white one dissappeared. It looked as though they were on the original object. once we had passed the object we saw 3-4 airport emergency vehicles with flashing orange lights racing down the runway towards the still hovering object/s. Looking back, the red lights were flashing, and between flashes they would violently, but in tandem, change altitude and orientation. As we came into Ramsgate, with nothing behind us but fields and an airport with the lights overhead, two police cars passed us heading to the airport at approx. 90-100 mph, with lights on but no sirens. we observed the object from home for approximately 40 minutes before it simply disappeared vertically upwards above cloud cover, but remaining the same orientation.
