Was this inspired by the article in the news about the RAF closing for a month in January?
My choices for closure would be:
RAF Brize Norton, RAF Basra.
And reopening:
RAF Gan, RAF Changi, RAF Sek Kong, RAF Seletar, RAF Tengah
RAF Butterworth, RAF Kuala Lumpur, RAF Kai Tak, RAF Muhurraq, Bangkok, Saigon, Belize etc etc.
And anywhere else hot and sunny.
