Yes, I remember Tarom's Ilyushin 18s too. Here's a link to the only photo I ever took of one, taxying at Manchester, almost exactly 42 years ago now!

And yes, Air Spain's DC-8s were noisy, colourful beasts. Here's a link to the only shot I ever took of one of these, again from 42 years ago:

But the noisiest and smokiest beasts of all, back in those days, were undoubtedly Spantax's Convair 990As. Sadly, I never photographed one, but perhaps someone else here will be able to post a link to a shot of one that they took back in the 1970s or 1980s? I believe one survives at Palma, allegedly for preservation, but it's not in very good condition. I caught a glimpse of it there in 2000.
