Season 6

A team of British engineers attempt to haul two historic A4 Pacific steam locomotives - each worth more than £2 million - more than five thousand miles across the Atlantic to the National Railway Museum in York. The A4 Pacific locomotive smashed the rail world speed record in 1938, thundering to over 126 miles an hour. To celebrate this record’s 75th anniversary the museum is shipping all the surviving A4 Pacifics to the UK for display. For specialist train trucker Andrew Goodman and his crew, this transatlantic train trek is their toughest challenge yet. The locomotives are no longer able to run under their own steam and need loading onto freight trains where there’s the constant risk these massive but fragile machines could disintegrate. Will the team haul the engines to the docks in time to load them onto their ship back to Britain?

A team of British engineers attempts to move a historic Canberra jet bomber over 400km from Coventry to Newquay, Cornwall, for a private collector. The vintage aircraft is in no condition to fly and consequently must travel by truck. Too large to be moved in one piece, the Canberra must be dismantled and reassembled at its destination.

An expert team of heavy haulers attempts to transport a massive First World War artillery gun 400 miles from the Royal Artillery in Wiltshire to a museum in Utrecht, Holland. This rare 200-ton gun was designed to be moved around the Western Front on railway tracks. But, for this move, the team has no option but to travel by road and sea.

We follow the engineers preparing the world's most advanced search-and-rescue helicopter for a trip on the world's largest airplane from New York State to its new base in Scotland. Search-and-rescue helicopter pilot Ben Clark patrols the North Sea from a base on the Shetland Islands and has one of the most demanding jobs in the country.

Wim Jelsma and Carin Koning want to build and move their dream home - one of seven floating mansions that will become a new waterborne community in the Netherlands.

A team of engineers attempts to build and haul a massive, brand new Search & Rescue Hovercraft 9,000 miles from Southampton to Sea Island, Vancouver in Canada. The Sea Island Coast Guard deals with hundreds of emergencies every year because of their dangerous tidal waters. Now they need a new type of all-terrain vehicle to cope with this threat and continue to help save lives. Engineers in Southampton, England have the answer. Griffon Hoverwork are at the forefront of hovercraft design and have struck a million dollar deal with the coast guard to supply them with one of their biggest ever - the AP1-88. Now all they need to do is get it there - which proves to be an epic endeavour.
