A Transatlantic Flight Used Only SAF

November 19, 2023, marked a special day for two North American firms – Gulfstream and RTX’s Pratt & Whitney. Why? A G600 business jet, made by the former, with two PW815GA turbofan engines manufactured by the latter, flew from Savannah, Georgia, USA, to Farnborough, Hampshire, United Kingdom, using 100 per cent sustainable aviation fuel (SAF). That made it the first transatlantic flight to be solely powered by SAF.

The Gulfstream G600 was fed with 100 per cent Hydro-processed Esters and Fatty Acids (neat HEFA), which lowers lifecycle CO2 emissions by at least 70 per cent compared to fossil-based aviation fuel. The SAF used was produced by World Energy and delivered by World Fuel Services.
