And, to the best of my knowledge and belief, were powered by Avons, not Olympus. Mind you, a mere four Olympus, without afterburner, in a Vulcan doing a demonstration take off at Farnborough remains a vivid memory from a very long time ago. It really did make your knees freeze, your back crack, and your liver quiver. But the Vulcan was even less of a GA aircraft, never doing joyflights.

I got told by ATC that he thought I must have woke up everyone in Western Sydney
Akin to an ATC response heard at YMMB many moons ago when an ex-Connellan Twin Bonanza reported "ready" for runway 22 - "the phone's off the hook, clear for takeoff"

They were sensitive neighbours way back in the 70's and quick to complain - and it hasn't stopped.

8 EE Lightnings in stream take off, ie 16 Olympus on afterburner, thundered like worlds end, the ground shook, yr body trembled like a leaf and it looked like God pulling a string of beads to heaven. Straight up until out of sight.
Brain boggling !

Great description aroa....God pulling a string of beads to heaven.

And Lightnings were kinda GA for a while but not anymore. Thunder City

Its most probable on the top five at least.
Did love the sound flying it and no shouting wife when one got home after a day in it. Yes, I could see her mouth moving but… :-)

How about the Cessna 'push me pull you', the Cessna Skymaster ? On approach with both props in fine pitch it was a real buzzsaw !

Great question. Many years ago, I was on the western apron at Moorabbin Airport when a Mitsubishi MU2 taxied, parked a short while (with engines running) then taxied away. The noise was absolutely unbearable; you really couldn’t be out there without HAVING to cover your ears.

Coincidentally, check out this article on XF-84H ‘Thunderscreech’

https://en.wikipedia.org/wiki/Republ...Thunderscreech

It was an early (1950’s) turbo prop. The tips of the props exceeded the speed of sound AT IDLE! This was the loudest plane ever produced, and could be heard 40 kilometres away. A short read, but well worth it!

What a joke!
BAC 1-11 = RR Spey and VC10 = RR Conway i.e. not the same engines at all.

I recall around 40 years ago taxying an MU2 at Essendon about 1 am in the morning night after night to do a freight run to Sydney. During the taxi out about half the houses next to the boundary fence would light up. I learned pretty quickly to have all before T/O checks done before leaving the apron so no delay at the holding point.
Sydney off course had a curfew so only turbo props with hush power could operate like, F27s, MU2s and other noisy bug smashers. Still the same today.

FP ....kakapo?
I stand corrected... Avon engines.
At that same Farnborough was a 4 Vulcan scramble, that repeated the EE SOUND performance.
Is the plural for Olympus , Olympii ? Bloody earth shattering that’s for sure.

And how graceful was that huge delta when a Vulcan on solo show did a roll just after lift off !

Often called the "MU-2 salute"

Just about GA how about the North American T-6 Texan/Harvard etc, but if that isn't GA enough for you try the de Havilland Canada DHC-2 Beaver. Its the supersonic prop tips what does it

That would be a Latin form of regular plural. As "Olympus" is a Greek word it would be something like "Olympodes", but in English the normal Olympuses would be considered correct.

I believe the mighty Saturn V is mankind's loudest sustained noisy invention to date - not sure how it compares with the Thunderscreech but probably in some way less unbearable to those near Canaveral during launches.

Few years ago a ground running Griffon interacted with a ground running Merlin in such a way towards where I was standing 100yds away that moving was imperative - some sort of resonance focused the noise in that particular direction I guess. Both engines sound great normally but this was painful. Might have been the faux props fitted rather than the usual Dowty Rotols...

Broad category. General aviation (GA) represents all civilian "aircraft operation other than a commercial aircraft operation or an aerial work operation". Private jets, like John Travolta's Boeing 707, including ex-military jets are considered GA.
