Here's a thought for you. On another forum the subject of airfields closing has also come up, and I sat down with a useful little book published in 2000 (this one:
) to carry out an exercise.
Including those that are at significant risk of closure in the next two or three years, I estimate that in the first twenty years of the 21st century the UK will lose about ten percent of its licensed airfields, both civil and military. It's an average of more than one a year, but the pace has accelerated in the second decade.
Leaves a nasty taste in the mouth.
