The Park and View Enclosure at RAF Waddington is already full ahead of the Canadian and BBMF Lancasters event on Thursday, along with the Vulcan.
Traffic on the A15 towards the base has been heavy this morning and there is a no parking order along the road throughout the day.
RAF Waddington apologised for any disappointment caused and said that everything has been done to allow as many people as possible to witness this historic event.
Viewing and flypast
At around 10am, the two Lancaster bombers, PA474 flown by RAF Coningsby’s Battle of Britain Memorial Flight and FM213 flown by the Canadian Warplane Heritage Museum, will fly to RAF Waddington, then be joined by the delta wing Vulcan Bomber XH558.
Two Hawk aircraft flown by 100 Squadron from RAF Leeming will also join the procession.
The Lancasters and the Vulcan will also host a flypast over south Lincoln between 1.30pm and 2pm, weather permitting, for the turf cutting ceremony of the International Bomber Command Centre on Canwick Hill.
