Turn up the sound on your laptop or mobile device and soak up the atmosphere of the #queenoftheskies Boeing 747400 spooling up to takeoff thrust!

3 different engine types were fitted on the Boeing 747400 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 CF680C2B1F on #virginatlantic 747 GVROM "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 GUNET, #OneAir #Cargo filmed this week at Heathrow and finally:

The Rolls Royce RB211524G powering #britishairways #queenoftheskies GCIVR, 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.
