The crew of Britain’s busiest search and rescue helicopter base will feature on television tonight.

Members of the team that flies Royal Navy Sea King helicopters from HMS Gannet in Ayrshire have played host to a BBC film crew as they took part in mountain rescue training in Glencoe and around Ben Nevis.

In 2009, the unit, based at Prestwick, set a record of 447 callouts – equating to more than one a day – rescuing 386 people, and breaking its own record of the previous year.

The film crew, from the corporation’s The One Show, spent a weekend with the helicopter crews, following them on the mountain rescue training and an air-sea rescue involving a submarine off the west coast.

Reporter Simon Boazman spoke to a number of the unit’s crew, including pilot Lieutenant Graham Bunney and Captain Michael ‘Jack’ Frost Royal Marines.

Lieutenant Bunney was undertaking his last ever weekend’s duty in the Royal Navy after 18 years’ service, and Royal Marine Commando Jack explained about how search and rescue skills gained in the skies above Scotland can be valuable for frontline operations in Afghanistan.

The One Show producer Kirk Barber said: “This is some of the best filming we’ve ever had. The variety was amazing and we got some excellent footage. The scenery was breathtaking and we were looked after really well by the guys at HMS Gannet.”

The crews of Rescue 177, call-sign for HMS Gannet’s Sea King search and rescue response, have also featured in the Five television series Highland Emergency.

The One Show, with new hosts Alex Jones and Jason Manford and guest Pamela Anderson, will be screened tonight, 18 August, at 7pm on BBC1 and will afterwards be available on the BBC’s iPlayer.
