Real Men

Jess, Martin and Stu regularly dive to 200 metres under the North Sea to satisfy our insatiable desire for oil. They live for a month in a tiny metal chamber in the heart of a ship, under pressure, so they can make regular excursions to the sea bed without suffering decompression sickness. Breathing a helium/oxygen mix and travelling to the sea bed in a diving bell that looks like a space ship, the trio exist in a bizarre and remarkable world that has rarely been seen before.

Steve is at pylon school, where he and his fellow hopefuls are hoping to join the linesmen who work at extraordinary heights, and in all weathers, to make sure that the National Grid delivers electricity to our homes 24 hours a day. If they have the head for heights, they might be able to join a team trying to rewire Britain. It's a job that sorts the men from the boys, and it's certainly not for everyone. Minicams, headcams and pylon cams record the work every high-wire step of the way.

An extraordinary team of men are nearing the end of a massive makeover of the Forth Bridge. We meet the scaffolders, the encappers, the grit blasters and many more who spend their days braving the high winds, the extreme cold and the high speed trains on one of the UK's most famous bridges. When these men are finished, the bridge won't need decorating again for another 30 years.

How many men does it take to change a lightbulb? By helicopter and ship, a group of men - and one woman - work around the clock to maintain the buoys, light ships and lighthouses that keep our shipping lanes open for business. On board ship, Nicky may be new to the job, but she proves that there's not much she doesn't know about buoys.
