I live in a former MQ at a secret Blunty RAF Base near Huntingdon and I agree, the jet noise last night did make a change from the usual Police helicopter! (which frequently shines its searchlight in ours and surrounding gardens)
I could hear a constant rumble but the jets seemed to hit re-heat each time I was about to drift into the arms of morpheus...
In fact, come to think of it, I was rehearsing a play in Bluntisham village hall one evening last week and we were interupted by a very fast, very low and very loud fly-by.
Might keep an eye out tonight and do some spotting!
