The fleet of 50-year-old VC10 planes have been forced to start flying passengers again after the 40-year-old Tristar transport aircraft have been grounded by technical faults.
Coupled with the poor weather there is now a backlog of 570 soldiers waiting to get home for Christmas leave.
But the use of the VC10s has caused defence chiefs to question whether the “airbridge” to Afghanistan has been “stretched beyond breaking point”.
Earlier this year the VC10s, which first came into service in the early Sixties, were ordered to be only used in an air-to-air refuelling capacity. The decision came on the back of the highly critical Haddon-Cave report that highlighted serious safety failings following the 2006 Nimrod crash over Afghanistan which resulted in 14 Service deaths.
The Haddon-Cave review severely restricted the VC10’s ability to carry passengers because it has an outdated ground proximity warning device.
However the aircraft, which can carry 124 people, is allowed to fly troops if a senior officer signs a waiver in exceptional circumstances such as a major war.
“This is something we don’t do in routine circumstances, only if it is a serious national emergency like war when peacetime restrictions are dropped,” said an RAF source...
Two of the 15 VC10s were retired this April after they had amassed a combined 81,500 flying hours.
Keeping open the airbridge to Afghanistan is a massive undertaking for the RAF with its ageing transport fleet that has to fly out 230,000 passengers a year from Brize Norton.
Already the recently bought C17 Globemasters are showing signs of fatigue with frequent breakdowns including one last month when Prince William was stranded in a Middle Eastern country for several hours on his way to Helmand...
