Long-haul carrier Emirates successfully flew a Boeing 777 on a test flight Monday with one engine entirely powered by so-called sustainable aviation fuel. This comes as carriers worldwide try to lessen their carbon footprint.
Flight No. EK2646 flew for just under an hour over the coastline of the United Arab Emirates, after taking off from Dubai International Airport, the world’s busiest for international travel, and heading out into the Arabian Gulf before circling back to land. The fuel powered one of the Boeing’s two General Electric Co. engines, with the other running on conventional jet fuel for safety.
