At Britain's busiest airport Heathrow, a team of international engineers race against time to move a state-of-the-art air traffic control tower across the world's busiest runway into position in a new terminal.
Find out how they narrowly avoid a lightning storm that threatens to strike down the glass tower in transit and precision-park it on to its new foundations.
Meanwhile, in Manitoba, Canada, fearless tower king Harold Minty has to shift five, 200-foot grain towers 20 miles, over a mountain frozen with ice and snow, to a new farm.
It's a rollercoaster ride as he fights his way through a vicious snowstorm, battling to stop this towering steel super-convoy from slipping off a snowy cliff edge.
