However, low level circuits at night and different circuit patterns as compared to the established VC10 and TriStar (and flying club!) patterns should certainly come under scrutiny.
Perhaps it's just a question of ''new boys' conforming carefully with existing requirements (e.g. straight ahead to 1000ft aal before turning downwind, with a 1500ft circuit height)? The C130s are relatively new to Brize, but some of the cowboy flying which (some) JATE and PTS crews occasionally used to indulge in, such as cranking the aircraft around shortly after take-off and thundering over Alvescot mustn't become the norm - there's no real excuse for that, no matter how much fun it might be. As for the silly sod in a WOTG C130 who barged into the circuit on an unannounced downwind join between 2 VC10s on a formation run-in and break...... But that was quite a while ago and I'm sure things are more controlled these days.
Beagle,
You seem to have the typical 'shiney' attitude towards a tactical aircraft, which is rather odd considering your Vulcan & F4 background. The C130 is not operated like an ex-airliner and whilst some things might have been done in the past in the name of 'fun' that doesn't preclude operating the aircraft in a different manner to the VC10 & Tristar. The C130 needs to do a great more visual flying than the rest of the Brize aircraft, especially at night, because that's how they're flown operationally.
As for 'cranking the aircraft around shortly after take-off and thundering over Alvescot' if we did we'd turn well inside that village as we don't need quite so much runway as you did.
