United Airlines makes first commercial flight on sustainable fuel

On December 1, United Airlines operated a flight that could serve as a turning point in the industry’s effort to combat climate change. For the first time, an aircraft with passengers has flown using 100% sustainable aviation fuel (SAF). A Boeing 737 MAX 8 (N77259) with more than 100 passengers on board and 500 gallons (1,892 liters) of SAF in one engine took off from Chicago (ORD), in the United States, to Washington (DCA). Alternative fuel is made from non-fossil raw materials, including used cooking oil. Currently, US airlines can only use a maximum of 50% SAF on board. According to the company, it is compatible with existing aircraft fleets. – https://aeromagazine.uol.com.br/artigo/united-airlines-faz-primeiro-voo-comercial-combustivel-sustentavel_7449.html
