Now I am going a bit of topic again, but what is the best aircraft sound, or noise if you will?
If you ask me; nr#2 – UH-1 “Huey” Helicopter where the crew is playing the Rolling Stones, loooooooadly.
nr#1; Any aircraft, caring one or more of the famous Rolls-Royce Merlin engines; spitfire, hurricane, battle, Lancaster, etc. but the best of them all (in my mind) a  P-51 Mustang fitted with the RR merlin
