747 TAKEOFF THRUST! Rolls Royce vs General Electric vs Pratt & Whitney. The best sound? #747

Turn up the sound on your laptop or mobile device and soak up the atmosphere of the #queenoftheskies Boeing 747-400 spooling up to takeoff thrust! 3 different engine types were fitted on the Boeing 747-400 - and in this film you can hear the sound of all 3 types - from the same spot at #londonheathrowairport Runway 27 Right. They all sound completely different - but which sounds best?? We've got first up, the General Electric CF6-80C2B1F on #virginatlantic 747 G-VROM "Barbarella" as she makes her last appearance at Heathrow on 3rd October 2020 heading for a new life with Atlas Air in the States; Followed by the Pratt and Whitney PW4056 powering G-UNET, #OneAir #Cargo filmed this week at Heathrow and finally: The Rolls Royce RB211-524G- powering #britishairways #queenoftheskies G-CIVR, seen operating the BA 195/callsign Speedbird 26E to Houston on 25 October 2019. Which do you prefer? Let me know in the comments! Cheers, Steve.
