Sad to see though Eric, there was a lot of effort in getting everything ready for service.
I seem to recall that no sooner had the A380 launched it was on to the B787 but I guess in reality there was a few years in between. Didn't seem like it at the time!
You mean A350 ?I seem to recall that no sooner had the A380 launched it was on to the B787 but I guess in reality there was a few years in between. Didn't seem like it at the time!

Indeed. The exhaust note used to crackle - which (I was told) was due to the exhaust gases exceeding the speed of sound.
With the exception of Concorde, I would say that the Trident was the noisiest airliner operating regularly in the UK.
The TU154 was very noisy as well, certainly pretty close to Trident levels.With the exception of Concorde, I would say that the Trident was the noisiest airliner operating regularly in the UK.

They used reverse thrust, which I heard from Hounslow West (about 5-6 miles away)
It would be interesting to hear a direct comparison. But having sat at the end of a runway listening to all sorts of 60s and 70s era jet airliners (including Tu154s), I will always say that the Trident was the loudest. The Rolls Royce Spey was just a noisy motor - and the Trident had three of them. Other Spey powered airliners only had two Speys (BAC-11 and Fokker F-28).
I reckon the Nimrod would have been even noisier (as it had four Speys) but you didn't get them much at civvie airports.
I don't remember any of the other engines producing that sonic crackle. You still hear it with rocket launches - but not jet engines.

I dunno.......Trident were indeed very noisy, but then again, so were the 4 x Conway's on a Vicky Ten......but perhaps a different type of noise. The Conway's used to vibrate your chest, whereas the Trident were a much higher pitched screaming sound.
The Caravelle was equally a higher pitched screamer, and not far off a Trident, considering it only had 2 engines.

Caravelles varied depending on what they had. The original Caravelles had Rolls Royce Avon turbojets (like the Comets 2,3 and 4) and the later Caravelles had Pratt and Whitney JT8D low bypass turbofans (like on DC-9s, the 727 and 737-100/200s).
I will still go with the Trident as the noisiest of the lot. At full thrust just before beginning the take off roll, the panels that made up the tail fin used to vibrate due to the sonic shock waves. I never saw that on any other airliner.
Obviosly, ALL of these older jet engines were massively louder than any civil airliners we have around today

Air France retiring their remaining 9 A380's by the end of 2022 and a further 3 expected at Knock for scrapping.
