We're looking at slot start today of 1416 for the flypast at Marham - arriving together - of the Vulcan, with both Lancs, a Spitfire and a Hurricane; then followed by their various displays before the slot time ends at 1445.
If in the area, then other stuff is displaying from 1200 through until 1630.
All in support of RAF Marham Families Day, which is a station event for RAF Marham personnel and families - hence, sadly, I haven't been able to cast the net wider to get others in.
