Showing the Standard Instrumentation Departure Routes he said it was impossible to fly exactly the same route as factors changed hourly, ie wind, weather, etc, there was some flexibility on landings but the routes remained constant within a 30 metre corridor; operating over a town centre many people would be affected so planes fly over the green belt. Mr Holding then explained the complaints procedure from call to tracking the culprit, the flight, the runway used, the height and speed, aircraft identity and type, operator, origin and destination. In all there have been 1600 complaints with 400,000 flights. Asked about aircraft flying directly over houses he said that planes flew in a straight line down a radio beam - the system is run by Air Traffic Control and enabled aircraft to land safely; also there is an elevation beam by which aircraft descend on a 3% scale. It was difficult to estimate the height and speed of an aircraft overhead coming in to land as big aircraft fly faster for more lift e.g., Boeing 707s would be flying at 200-250 mph at 1800 feet but because of size appear to be lower and slower. Answering a question on air space Mr Holding replied that airspace between planes is 6 miles and 1000 feet, and
