In the good old days
Edinburgh was a training centre for NATS. Pilots were often asked if they could accept an SRA or radar vectors for controller training. There was three runways, sometimes all being used at once. Great fun!
Then some bright spark figured out more money could be made by parking cars on runways instead of letting aircraft use them. Introduce computerised flight strips and pay off assistants. Aah! Privatisation.
Edited to add; Edinburgh 114000 movements per annum. 1 runway 1 arr/dep frequency.
Orlando 303000 " " " 4 runways 5 arr/dep frequencies
Jeez up to a couple of years ago aircraft had to backtrack RWY 06/24 at Edinburgh!
