Quiz - What was the Worlds fastest subsonic airliner?

It was the Convair 990 Coronado although the Trident was not far behind.
The Comet was only a .72/.75 airplane.
The VC10 would probably be capable of Mach 1 and one was rolled when the F/O got it wrong on a Dutch Roll exercise. Although to watch the horizontal though the periscope while that was happening would be rather exciting.
BOAC also had a 707-436 that they lost control of in the same exercise and that was recovered over the sea off the SW UK coast at a very low altitude. It is believed to have gone supersonic as they pulled over the top on recovery.
But the fastest was indeed the Coronado and they have all gone now after Spantax got rid of them.

They all worked mate, you need to refresh your browser sometimes in order to see postings that are very recent. pressing shift + refresh symbol works to force a refresh and not used a cached version of the page
and also no matter what your browser does don't use the back button to go back to the submit page and press submit again, chances are that your submission was taken , but that your browser went funny after that. Easiest way I find is to highlight what I have written then copy it so I can paste it back if neccesary, saying that I've never found that my post hasn't gone through, except when I've put my password in incorectly.

You are quite correct. CX had a fleet of CV880's. And indeed the CV990 was the fastest in normal cruise. Several I have noted earlier have the incorrect information about wing sweep. Boeing 707, L1011 are at 35 degrees. DC-8 (-20 series, the first to go supersonic) is 30 degrees. The Boeing 747 is at 39 degrees. There is no western 45 degree swept wing subsonic airliner in service. And never has been.

I only ever witnessed cv990s at an airfield. I seem to remember them being a bit fastish on the approach as giving an SRA to one was always "interesting" . They were extremely dirty looking on departure, quite often giving rise to jokes about needing RVR readings for following aircraft.

A couple of years ago I had a jumpseat ride in a an Avial TU154 from Moscow to Kogalym. In the cruise at 11700m over Siberia, we were indicating M0.97. The captain reckoned he could stand the power levers up a little bit more, but then I might start getting tunnel vision!

To explain why some of the posts here might not make too much sense ........
I have removed 12 posts from Speedbird 48 which all said more or less the same thing. The advice about refreshing browser caches is sound and saves us a lot of work here at the Towers if followed

Not only is the CV990 the fastest (although the Tu154 info is interesting), but it set speed records which will never be broken, since it flew in the days before (a) the 250 kts below Fl100 rule was introduced and (b) there was no traffic, so crews would fly at breakneck speed direct to the outer marker. Certainly on almost every US domestic route the a/c was ever flown on, the speeds set by the CV990 are untouchable and will remain so forever.

It was the Convair 990, Coronado last flown by Spantax and Nasa had one for a while. It could be told apart from the 880 by the big lumps on the trailing edge which reduced drag.
The Trident was also very quick but the Comet was only a .72/.75 airplane.
