707 vs. DC-8 noise

When I first moved down to the south I lodged not too far from gatwick,I looked up at a very noisy (and lower than usual) DC8 climbing out….with smoke trails out of 3 engines :D.
Aha that is why he was lower 😀

Ah yes…real airliners 😀
Have flown in both …
From memory istr that the DC8 had a little more cabin conditioning noise (roar) than the 707.
In a way I preferred the DC8 because you couldnt see the outer engines bouncing up and down in turbulence 😀

Totally agree, having flown on an SAS DC8 Srs 63 and a BA 707 (a 320C I think). Is anyone flying pax today on the DC8? I know that you can still get a ride on an Iranian 707

I sure wasnt worth much by the time I got there LOL 😀

I know that feeling! 😀

Yes and many thanks to the swissair DC8 hosties that kept handing out free drinks all the way from Zurich to Harare…I sure wasnt worth much by the time I got there LOL 😀

You can hear that distinctive whine quite clearly here

What an immense sound! I’m tremendously envious of anyone who was lucky enough to fly on these old beasts. Amazing sound and stunningly beautiful aircraft. 🙂

Those videos kick ass!
That’s the closest I’ll ever get to flying those legendary jets.

The pre hushkit 1.11 with water injection was the second only to Concorde at the start of its takeoff roll:D

Coming to rattling of windows, I still don’t take too kindly to th IAF IL 76 that leaves DEL every now and then at 2 am. 😎

Amid all of this nostalgia, let’s not forget the glorious noise of our home-grown Comet and VC-10 and the ‘Pocket Rocket’ itself, the (pre-hushkit) BAC 1-11.

The VC-10 is the only aircraft these days that rattles my windows on take-off from MAN. An increasingly rare event now, sadly. 🙁

Ah, the 707 and DC-8, when noise and pollution were not nearly as important factors as they are today.

We have indeed come a very long way. Especialy when an engine of today with a diameter greater than that of the DC8 and 707 fuselages makes less noise than just one of their engines!

Indeed, I just wish the environmental campaigners and NIMBY’s would acknowledge the leaps and bounds made by aviation in a relatively short time of jet operations, and would acknowledge the continued improvements going forward.

I’m fairly certain the rate of fuel consumption improvement in cars has not improved at such a rapid rate by percentage.

Wasn’t it the water injection some 707s used that generated the black soot?

I also noticed the thick soot that blasted out of the engines.

It’s the worn piston rings Mr Totty! :p

They both make a screaming noise from what I can remember. Wasn’t the DC-8 re-engined with CFM 56s?

I’m not old enough to have flown on either type, but remember watching them take off from AKL as a boy.
All I can recall is that both were niosy, but particularly the B707, whose scream on take-off was excruciating (but very enjoyable). I also noticed the thick soot that blasted out of the engines.
More recently at an airshow, I watched a Nimrod perform a low pass and then a steep climb. The noise and exhaust plumes were very 707-like to my ears. Then, a Virgin A340-600 did exactly the same and its engines on full-throttle could barely be heard.
I love old airliners and would give anything to fly on one, but in the noise and pollution stakes, we’ve come a very long way.

As one who has flown many times on the 707 and the DC8 since their introduction in the late fifties..i can honestly say i never noticed any difference in engine sounds between the 707, DC8, DC9, 737 and 727..they all had a high pitched whine on take off..i only ever noticed this so called buzzsaw effect with the introduction of the Hi bypass engines

I’ve never flown on either jet, but I have been a lifelong admirer of the overall design — and esthetics of the silhouette — of both the 707 and DC-8.

My observations over the years have been like this:

What I really noticed with the addition of hushkits to the JT3Ds in both cases, was the near total disappearance of the buzzsaw noise in the DC-8.

Also, in both cases, even without hushkits — the JT3Ds, to me, always had a less harsh exhaust boom than did the old JT8Ds that powered the original 737-200, 727s, and DC-9s.

Anyone agree?

Glad to have helped and thanx for those clips. Thinking back, the loudest “buzzsaw” visitor to us used to be the Boeing 720Bs os the Danish airline Conair. BTW I cannot take credit for the term “buzzsaw” that was told to be by an SAS engineer on a DC8-63 turnround many moons ago!:)

Sorry I hadn’t replied soon, I saw your reply just now

Well, thanks, that’s what I wanted to know, and what I suspected also.

I love the buzzsaw sound as you call it. I haven’t heard any other engine make it just like that. Later came engines with larger fans, which make a different kind of buzz, deeper, nothing like 707.

Here is a couple of clips with some classic 707 buzz:
