It was a news story a few weeks ago.
The enthusiasts were rather too, well enthusiastic and were in an area with warning signs about low flying aircraft - but they were not trespassing.
This is the first Typhoon I've seen in 41(R) Sqn colours, an Operational Evaluation Unit, it also has Tornado GR.4's and until 2010, Harriers.
The Typhoon OEU was 17(R) Sqn but that unit will now be the F-35B OEU.
Apparently they call this area of the perimeter the 'head chopper'.
As seen here, watch out for the Vulcan at the end;
In related news, the legendary 617 Sqn, The Dambusters, will stand down as a Tornado GR.4 unit in late 2014 but recommission in 2016 as the first RAF F-35B Sqn.[Edited 2013-08-09 01:45:09]
