The ever helpful Group Travel Office had warned us that this was a 'group of foreigners'. It would indeed have been helpful to have known what language they spoke but never mind.
Turned out they were Germans. Geoff's German is limited.
As they waited for the train at Settle an RAF Tucano, probably from Linton-on-Ouse flew over. These RAF trainer aircraft are frequent visitors to the Dales. They handle like jets, are good for hill-hopping and have the look and sound of a Spitfire. Visitors ofter think they are Spitfires.
Geoff, on seeing the aircraft went onto auto-pilot, as it were. "Don't worry" he said, "it's one of ours".

Here is a soundless video of a pair of Tucanos taking off from Linton and enjoying themselves over the Lake District, Derbyshire and the Yorkshire Dales. Definitely one to be watched in HD, but not on a full stomach. Look out for the Ribblehead Viaduct.
