The old farm house was the airport administration building until the 'new' terminal opened in (I think) 1965. It then became the Flying Club Bar. Use to finish shift at 22:00, into the bar for a pint or six and then back in the following morning for a 08:00 start. :-) Closing time was non-existant.
The 'greasy spoon' (aren't they all called that?) was a separate building between the control tower and the farm house.
The old tower and Building 50 (the wooden building) were demolished in the early 2000s.
