Electricity - Power Cable Repairs - River Usk, Wales

Four Central Electricity Generating Board engineers are suspended high above the River Usk, Wales, during repair work to damaged overhead power cable lines. The repairmen were lowered down to the damaged cables by a British Airways Boeing Chinook. Carrying out the repair work this way, rather than using the conventional trolley, will save an estimated 140,000. Using the trolley system, taking a week to complete the work, would cost about 40,000 a day in 'lost electricity', where as using the helicopter to complete the work in 30 minutes cost just 100,000 (Photo by PA Images via Getty Images)
