The London Eye currently has EDF Energy as a sponsor. The EDF stands for Electricité de France, of course; just as 20% of the iconic London Buses are operated by Deutsche Bahn - the German railroad company.
Great view of the City of London taken from the western walkway of Tower Bridge.
My wife and I thought it ironic that we should see a Virgin balloon having flown Virgin Atlantic but we were both thankful that Virgin Atlantic fly Boeing 747s and not balloons such as this!
