Our travel day was long, with an 8 hour layover in Heathrow Airport, London. Not recommended! But now we are in Lyon, where we stay for another four nights and the Goldschmidt Conference (geochemistry).

Our plane, Boeing 777, at DEN (Denver International Airport).

A bunch of HUGE planes (Airbus A380) in a row at London Heathrow Airport.
