A US Air Force (USAF) F-15E Strike Eagle fighter aircraft has performed the first flyover using green biofuel.
The plane, from Seymour Johnson Air Force Base, North Carolina, US, flew over Citizens Bank Park baseball ground before a game.
The jet used a 50% blend of traditional jet fuel and synthetic biofuel derived from plant oils grown in north-western US.
USAF energy deputy assistant secretary Dr. Kevin Geiss said the air force remains committed to reducing foreign petroleum usage and hopes to use biofuel blends for the entire fleet of manned and unmanned aircraft.
“This flyover demonstrates the air force’s leadership and commitment to use alternative fuels, allowing the service to collect additional performance and flight information,” he added.
The USAF has been testing and evaluating biomass fuels derived from three different feedstocks: camelina (plant seed oil), beef tallow (animal fat) and various waste oils and greases.
