On March 25 and the 29th, 2 airbus A380’s were flown with 100% renewable fuel. The first flight was a flight around toulouse and then the second one was from toulouse to Nice. Both of these flights were used with SAF cooking oil. By 2035 airbus hopes to use this fuel to slow down the emission production. This would change aviation forever and it would be very cool to see in the near future.
Good to see that cooking oil for fuel idea is improving, if I recall Air Canada did a flight or two a good few years ago with cooking oil (I don’t think 100% cooking oil though)
