Have been in the river the last 2 days and the plane taxis under the motorway bridge. The wings fit between the pylons with a few meters spare either side.
The river is not busy at the moment, but come Bream season, this plane will have major trouble navigating under that bridge with the boat traffic.
Oh, and this business is well and truly up and running.
