AIR FORCE AFGHANISTAN Five, 8pm

This penultimate episode of the documentary series, chronicling life for British servicemen and women stationed at Kandahar air base in southern Afghanistan, sees the Naval Strike Wing make a dramatic dash to assist ground troops in Helmand, a hi-tech unmanned jet take to the skies and an RAF corporal devise an enterprising idea to raise money for charity.

As the episode opens, Naval Strike Wing pilot "Tremors" gets the call to scramble to a village 140 miles away in Helmand province where British soldiers have come under attack. Within 15 minutes of taking to the air, Tremors is flying 30,000 feet above the combat zone and uses the sniper-targeting pod beneath the fuselage to survey activity on the ground.

The long-range cameras, however, reveal that there are civilians - including children - in the area, meaning that the bombing mission must be aborted. Tremors returns to base with all his missiles intact. "It wouldn't have been appropriate for us to have waded in," he says. "The bad guys simply melted away like they tend to do around here."

For fellow Harrier pilot, Lieutenant Simon Rawlins, using the jet's immense firepower is not something he takes lightly. "I personally don't take any satisfaction dropping bombs on people," he says. "It's a last resort."

Elsewhere this week, a new addition to the fleet is unveiled, the hi-tech Reaper unmanned aerial vehicle, a remote-controlled warplane operated by pilots on the ground, and Corporal Jim Fowler of the RAF regiment has decided to make a charity calendar starring the good-looking guys and gals stationed at the base.

Armed with just a camera and the gift of the gab, he sets to work, much to the delight of onlookers.
