Yesterday the Reds were flying around Farnborough area at around 7:30 PM - that must have been after the Air Show timings. Any idea why they were flying that late? Not complaining - enjoyed every moment!

I believe it was for validation.

What he said. The weather was too bad thursday evening for them to fly for a validation, so at ultra short notice (and probably missed by most aviators) the hours of operation of Farnborough RA(T) Areas 1 and 2 were extended to 1900 UTC; how many pilots noticed that I wonder!!
