The 737 also managed to break the old sound barrier. Not on a very happy occaision though. It was the Silk Air that did a power dive and that subsequently crashed in Sumatra.
I would be interested to know more about this DC-8 that broke the sound barrier. On what kind of occaision did this happen and what was the result ? Must have been some interesting mach buffet I should think. Any more info, Will ?

There was also a 727 that was involved in an uncommanded unilateral slat deployment over Michigan sometie during the '60s I beleive. It took a nose dive and fell about 30,000 feet before the pilots recovered. It likely broke the sound barrier on its way down - but survived.
Also, I heard a rumor that the P-38 might have been the first aircraft to break the sound barrier, not the X-1. During terminal-velocity dive tests for the plane, one pilot pushed teh envelope a little too much and lost control. He recovered, but the speedometer was stuck at a speed that would have been above Mach 1 for the altitude where he lost it. But nobody knows for sure so Yeager still has the definite credit.

I had the same problem when I put up that question about the AVRO C.102 Jetliner. Nobody took the bait and tried to claim that Boeing was the first company in North America to fly a jet airliner prototype.
These guys are good.
