On the way to Washingon DC

Vapour trails are such an infrequent sight these days I was drawn to point the camera skyward at this one that passed overhead when I was eating my alfresco lunch. 

The internet told me it was Flight SK925 (an Airbus A330) going from Copenhagen to DC and was flying at 36000' at 454kts on an almost due westerly course. It is still airborne as I type, but going to be 15mins late on arrival. Just in case you know anyone who is due to meet it.
