You'll find that it was G-MCGE which is working out of Humberside on its 3 month lead-in period. This is the aircraft that was in the Lakes a few days ago to introduce the Lakes MR teams to 21st century aviation.
Just the one aircraft at Humberside so far and the same at Inverness (G-MCGF).
(ADS-B reveals not quite all but most of it.)
