Someone on facebook (See edit) said there's going to be an event on the 21st which should have been at Coningsby but was cancelled due to poor infrastructure so was moved to Waddington. Apparently it'll be a pay event with all 3 landing at Waddington but it will be like the air show weekend with no parking and road cones everywhere. I know nothing though

and I can't even find where I read that so I can't even provide a link.
It COULD BE just rumour and speculation at the moment BUT On the 21st they are doing flypast's at Marham and Wattisham on the way to Clacton, so they are out and about.
::EDIT:: Found it.
It's straight from John who runs the WAVE.
