I'm on a crowded commuter train rather than the quiet one I was hoping for. That's because, as I rounded the corner at Guys Hospital, I heard a roar of engines, and a trimotor aircraft flew by, tracked by a helicopter.
As I reached the concourse outside London Bridge station, I saw it completing the first of two passes by the Shard, and I waited outside to get photos of the second pass.
I don't have a good lens with me for aviation, and nor do I have the functioning shoulders which would have helped, and an achingly long shutter lag placed the aircraft behind a crane tower for the closest shot. But look out for some massively over-enlarged fuzzy dots later.
Not sure what it was, as there were a number of similar aircraft at the time. First thought was a Junkers Ju-52, but I don't think that's it. I think there were Fokkers and Sacchis too in the same format, but I suspect this was a Ford.
I'll gewgall later. But it was an exciting moment.
