Here's a question for you... What do you spend your hard earned on when you've sold 82 billion cans of fizzy pop? Well, helpfully, energy drink doyens Red Bull can help answer that.
No stranger to the world of aviation, Red Bull's founder - Dietrich Mateschitz - and his family have spent a small fortune amassing an incredible collection of aircraft based in a captivating custom-built, glass-and-steel-constructed hangar at Salzburg Airport. Red Bull's staggering fleet includes examples of the North American P-51 Mustang and B-25 Mitchell, the Lockheed P-38 Lightning, the world's only flying Bristol Sycamore and the last Douglas DC-6 to be produced, which was used for a time as Josef Broz Tito's personal aircraft.
But the Flying Bulls collection isn't just about the greats of historic aviation as they like to push the boundaries of what's possible every now and again. Red Bull themselves have leant their support to those who like jumping off and out of things - be they cliffs, buildings, bridges, helicopters, aeroplanes and even balloons which have floated up to the edge of space.
