Satellite falls on Canada?
In article 7ebeb47a-1109-48c1-a67a-a22a7ff527d6
@db5g2000vbb.googlegroups.com, says... NASA and apparently even Fred doesn't really know, or more likely they don't wish to tell us exactly where that debris fell to the ground. They're talking as though it stayed pretty much as a whole unit if the debris field was only worth 500 miles. Final Update: NASA's UARS Re-enters Earth's Atmosphere http://www.spaceref.com/news/viewsr.html?pid=38584 From above: NASA's decommissioned Upper Atmosphere Research Satellite fell back to Earth at 12 a.m. EDT (0400 GMT), as Friday, Sept. 23, turned to Saturday, Sept. 24 on the United States east coast. The Joint Space Operations Center at Vandenberg Air Force Base in California has determined the satellite entered the atmosphere over the Pacific Ocean at 14.1 degrees south latitude and 189.8 degrees east longitude (170.2 west longitude). Jeff -- " Ares 1 is a prime example of the fact that NASA just can't get it up anymore... and when they can, it doesn't stay up long. " - tinker |

Pat Flannery scribbled something like ...
Poor Canada, first the Soviet satellite with the reactor on it, now this: http://www.indianexpress.com/news/na...p-plunges-back -to-earth/851157/ Isn't the revised report that everything ended up in the South Pacific? But we can try again with Rosat. The Germans made it smaller, but the mirror (or mirrors?) are expected to be among 30 pieces surviving because they are especially heat resistant. I'm not sure if Rosat has beryllium tanks like UARS did, but it would be interesting to compare expected and actual piecework. /dps |

Obviously objective evidence doesn't matter to FUD-masters like yourself, so it's perfectly understandable how you would either implode or self-destruct if having to review any objective evidence that proves otherwise about WTC7 or anything else going against the mainstream status-quo. You seem rather bipolar. Doesn't "motive, means and opportunity" mean anything to those of your bipolar kind? http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |

The Earth-moon L1 (Selene L1) with as little as 20 atoms/cm3 to contend with, might be a super terrific location for the next generation space station or gateway/oasis, though actually Venus L2 would be considerably cooler. http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |
