BBC Engineering Giants

Engineer turned comedian Tom Wrigglesworth and Rob Bell, rising star of mechanical engineering, climb on board Victor X-ray, a 200 ton, £200 million Boeing 747. This jumbo jet has flown over 36 million miles in its 14 year life with British Airways. Now it will be broken into tens of thousands of parts in the airline's maintenance hangar in Cardiff, before being painstakingly reassembled and certified fit to fly again. This is the first time this complex process has ever been filmed and it provides fascinating insights into just how a 747 works. Rob and Tom also visit the UK's largest plane salvage centre in the Cotswolds to discover what happens to a 747 when it reaches the end of its working life, and discover how valuable parts are stripped for resale before the carcass is torn apart to be recycled.

Engineer turned comedian Tom Wrigglesworth and Rob Bell, rising star of mechanical engineering, tell the story as an entire North Sea Gas installation, the Lima Platform, is pulled from the sea by floating cranes, brought back to Newcastle, and then torn into tiny pieces for recycling. But the platform is not just thousands of tons of steel. It was once home to the men and women called the North Sea Tigers. They pioneered gas and oil exploration in the UK and now some of them are ending their careers as part of the decommissioning process. As the gas platform is stripped down, these engineers reveal the secrets of this vital part of our energy supplies, but they also reveal the emotional bonds to the engineering marvel that formed such an important part of their lives.

Engineer turned comedian Tom Wrigglesworth and Rob Bell, rising star of mechanical engineering, climb on board the Pride of Bruges, a massive, 25,000 tonne North Sea ferry as it is brought into dry dock in Newcastle. It has been ploughing the route from Hull to Zeebrugge for over a quarter of a century and is now in need of the biggest overhaul of its life in an attempt to prolong its seaworthiness for another decade. Tom and Rob also travel to Europe's largest ship breaking yard in Belgium, to discover what happens to ships at the end of their lives. As they watch massive hulls being torn apart, they gain more insights into how a ship works and how their massive carcasses are recycled.
