07/09 Huddersfield Flypast?

Hi Guys,

Any chance someone knows which aircraft have just done a flypast of Huddersfield, and the reason for it. (Roughly 19:20)

The 10/11 ship formation headed south-bound after the pass. My Grandad (RIP) who has recently passed away, had a keen interest in aviation and travel, so although the reason for this flypast wasn’t him – it’ll always be remembered to my family as a mark of his life.

Any information would be much appreciated.

Sam
