Vulcan Bomber 'Howls' into a near vertical climb on full power and rolls upside down

Vulcan Bombers last pass at Southport Airshow 2015. The Rolls Royce Bristol Olympus 202 engines howl into full power and she roars into a near vertical climb and does a full upside roll at the top.... the best display I have ever seen her do; because she is over the sea and can push the envelope! a credit to her pilot's skills.
