In a historic move during the Trooping the Colour ceremony, the Royal Air Force's Red Arrows aerobatic team utilized a 40% blend of sustainable aviation fuel for their flypast over London.

The initiative aligns with King Charles III's advocacy for environmental sustainability.

The biofuel, derived from waste cooking oils, powered both the jets and their signature red, white, and blue smoke trails.

This marks the first known instance of such eco-friendly fuels being used simultaneously by a national aerobatic team, highlighting the UK's commitment to reducing carbon emissions in aviation.
