An historic aircraft will set off from Cambridgeshire this morning for an aviation adventure.
The Catalina G-PBYA plane will leave the Imperial War Museum Duxford to undertake the 1913 Circuit of Britain flight.
The 1,600 mile route was made famous when it was first flown 100 years ago by pilot Harry Hawker and mechanic Harry Kauper in a Sopwith Waterplane.
The crew is hoping to follow the original route as closely as possible. It is expected to take around five days.
