RAF completes first flight powered by used cooking oil

Fighter jets could fly on fuel made from old cooking oil after the Royal Air Force completed its first net zero flight. 

For 90 minutes, the RAF Voyager flew over Oxfordshire powered purely by 100 per cent sustainable aviation fuel.

The flight, which took place on Wednesday and replicated an air-to-air refuelling sortie, was the first time that a military aircraft of its size, or any aircraft in the UK, had completed such a feat. 

RAF Voyager required no modifications to handle the sustainable aviation fuel.

A defence source told The Telegraph that if the RAF could replicate aviation turbine fuel, a form of paraffin that all jet engines run on, “then it could work on future fighter jets”. 

“That would be part of the plan for making the RAF carbon neutral in due course,” they added.
