New Delhi, Nov 28 : Rolls-Royce ‘Flight 100’ -- which is world’s first 100 per cent Sustainable Aviation Fuel (SAF) flight -- took off from London Heathrow airport to New York, JFK on Tuesday.

The flight marked the culmination of a year of radical collaboration, to demonstrate the capability of SAF as a safe drop-in replacement for fossil derived jet fuel, compatible with modern engines, airframes and fuel infrastructure.

Flown on a Boeing 787, using Rolls-Royce Trent 1000 engines, the flight marks a world first on 100 per cent SAF by a commercial airline across the Atlantic.
