Jon, an even more nit-picky [and knowledgeable] person than you or me has PM'd me the following. < Sorry Maurice, I just couldn't resist. The Zenit never really "burned". The failure went something like this: The Zenit had 3 on-board computers to control the major functions of the powered flight: ignition, fairing separation, stage separation, etc. As a means of redundancy, each time a critical event in the flight was about to occur, the 3 computers would "vote" on what to do. When it came time to light the 2nd stage (about 5 minutes into the flight), two of the three computers had failed, leaving only one remaining. The 3rd computer, functioning properly, voted to ignite the stage. However, it did not hear any other votes (from the failed computers) and declared itself a minority (1 out of 3). Since only a minority voted to light the stage, all propulsion systems were shutdown. Had the 3rd computer been programmed correctly, it should have counted its vote as a *majority* (1 out of 1), not 1 out of 3, and all would have been well. So, in the final analysis, the rocket flew for 282 seconds, shut itself down, and coasted into some swampy land in Siberia. The correct term would then be "crashed and sank". As far as I know, no explosion or combustion caused the failure. > Full, broken-english explanation available at:yuzhnoye.kiev.ua ... at the very bottom of the page. So, once again we learn about the limitations of democracy as the most wonderful institution in existence. I do NOT like the expression 'crashed and sank' in relation to Globalstar. The stock price seems to be operating a little like that. At least it's in good company with the Nasdaq. Anyone's knuckles starting to whiten a little? This is getting to be quite a bit of fun.
