On the 28th November 2023, a plane flew from London to New York. For the first time in history, this transatlantic flight was 100% powered by sustainable alternative fuels. This rounds off a promising year for sustainable fuels in aviation. Earlier in 2023, ReFuelEU Aviation Regulation was adopted by the European Union, mandating a 70% sustainable aviation fuel blending obligation by 2050.

Flytrex is one of the leading companies in autonomous drone delivery. In 2022, the company reported a 765% increase in deliveries after achieving regulatory approval from the Federal Aviation Agency to begin its automated drone delivery services in the Dallas-Fort Worth area. Founded in 2013, Flytrex has made significant efforts in developing their autonomous drones for delivery services. However, as a common barrier for the drone industry, it takes Flytrex a long time before they get the green light from regulatory bodies.
