...flights. Boisjoly worried in particular about Shuttle Mission 51-C in January 1985, in which the seal temperature had been 53 degrees (although the air had warmed to 66 degrees by the time of launch). When the spent boosters were recovered from that flight, what Boisjoly described as black soot "just like coal" was found behind a primary ring in one booster, indicating that gases had blown past the first ring. Although erosion had also been found after flights in warmer temperatures, 51-C had been exposed to overnight lows in the 20s and had more extensive ring damage. Boisjoly...
...sediment taken from Denmark, Spain and New Zealand. To their surprise, all three samples contained carbon that had been deposited at a rate 10,000 times as great as carbon in the layers immediately above and below them. It was bunched together in the fluffy patterns characteristic of common soot. Says Anders: "It's like the stuff you see in the flame of a candle." He believes that the soot almost certainly is a remnant of vegetation consumed by fires...
...outward at the speed of sound, igniting forest fires from North America to Asia. Several hundred billion tons of plants and animals would have been incinerated, sending great scarves of black smoke to join the impact dust in the stratosphere and circulate around the globe. What is more, because soot does not rain out as easily as dust, the protonuclear winter would have lasted much longer than it would through obscuring dust alone. Most plants and large animals that survived the blast, the fire and the lethal clouds of carbon monoxide would have succumbed to the climatic changes. But smaller...
...divorcee found work cementing shoes in a factory and rented a two-story house. She worked extra hours to pay her bills and, according to the Washington Post, would arrive home "in jeans and a sweatshirt covered with soot and glue, too tired to change clothes." Shalel Way, a friend in Skowhegan, told the Post that Barbara would complain, "Johnny Walker did this to me." She shared her secret with Way, even asking for a Tarot card reading to help her decide whether to tell the FBI. She claimed that John would get drunk, call her on the phone...
...Clouds of dust and smoke block sun's rays, then spread over vast areas of the globe, causing ground temperatures to fall. Much of the soot in lower troposphere is eventually washed out by rain, but clouds higher up continue to block sun for weeks or months. The particles that reach stratosphere could remain for a year or more...
