High-fat flight is first jetliner to make fossil-fuel-free transatlantic crossing from London to NY

The first transatlantic flight by a commercial jet powered solely by so-called sustainable aviation fuel has flown from London to New York. The Virgin Atlantic flight aimed to achieve what supporters called “jet zero" to make air travel more environmentally friendly. But large hurdles remain in making the fuel widely available. While governments have long talked about decarbonizing air travel, the transition has been moving at the pace of a dirigible. Sustainable aviation fuel reduces greenhouse gas emissions by about 70% but is in short supply.
