Tim, what traffic do you have installed? I have modified FPs of
- Jagel (JY Tornado),many times a day
- RAF Gütersloh (JY Harrier), each hour for many times
- RAF Wildenrath (JY Phantom) (just same turn arounds like the Brüggen Tornados each 15 Minutes between these two bases...)
- RAF Lyneham (C-130 Herc), but not sure at which time they do appear...
- RAF Lakenheath (JY F-15), many times a week
- RAF Bentwaters/Woodbridge (JY A-10, C-130), several times a day
- RAF Brize Norton (C-17), several times a day
...to appear at RAF Brüggen.
I could attach my flightplans here for testing - there may be some of these aircraft appear for sure

Regards, Manfred.
