Have a look at the Notams for this area on weekly basis. Exercises at Sculthorpe USAF C130 and Ospreys many days into late evenings. Often Hawks etc involved with mock attacks on Sculthorpe at other times. Also tactical refuelling practice for Lynx, Chinook etc at Little Snoring from time to time and helicopter exercises at Weybourne. Live at Little Snoring and pretty busy most evenings. What happens when USAF moves to Germany from Mildenhall is another question.
