Not quite what you hoped for Nick but hope this helps a bit
"Subject to suitable weather and no technical issues, we plan to be airborne this Sunday and there will be two great vantage points for our supporters to see XH558. We ask that you adhere to these two locations to avoid any major disruption to the attendees of the Falklands Memorial dedication in Staffordshire, as we carry out a flypast in honour of those that were affected by the conflict.
Your best opportunities of viewing will be either at Robin Hood Airport around 11.30am, or,
if you are in the Midlands, at RAF Cosford, near Wolverhampton. XH558 is expected overhead the airfield at 12.25pm, followed just over 30 minutes later by the BBMF Lancaster. With several other attractions and free admission to the museum, this would make a great day trip for the whole family"
Edit: I hope to be at Finningly for 11am ish.
