yesterday the Discovery Channel had a show called The calendar disaster this is what I found interesting, basically its saying the cabin where the crew was did not explode they were alive for the two minutes 207 mph fall to the ocean!! afterThe investigation into the Challenger disaster by NASA determined that some of the crew did survive. Three of the crew turned on their airpacks. The Challenger exploded at an altitude of 47,000 feet while it was still climbing at a high rate. It reached a peak altitude of 67,000 fleet before it fell back to the ocean. At that altitude, the crew would not have been concious. So, they may have survived the fall back to the ocean but they would not have been concious due to the severe shock and the loss of atmospheric pressure. Answer improvement from GTG: Only one crew member turned on air packs. Judith Resnik turned on her own, plus she turned on the pilots and the commanders. She was a mission specialist who was sitting behind them both. It is not known if the pilot or commander were conscious at the time, but it is know that she must have still been consious and aware that a disaster was happening. Answer improvement from Jensener: No, both of you are wrong, sorry to say. ALL the astronauts were alive when the challenger exploded, they were alive during the about 4.5 mile drop to there death. The reason for this is that the capsule is made of extremely durable and strong Titanium covering the outside as well as some the inside, so when it exploded they probably got tossed around and knocked out, but there is evidence that they were all alive during the free fall; they did biological studies from a small group of elite Navy divers that went down to the challenger wreck and took study. I know this for a fact because my neighbors, wifes, brother was one of those elite divers. All as i can tell you is that they were alive before they hit water, says Jodie Halls brother, (Classified Name). So whatever other people tell you that only some survived, or that the all died the moment of explosion, is INCORRECT. This is a 100% fact and if you do enough research into NASA and the U.S. Navy about this, you WILL find out that I am NOT LYING. CAPE CANAVERSAL, Fla. -- This week marks the 20th anniversary of one of the most enduring images of the 20th century -- the Challenger accident. One of the mysteries of the tragedy concerns the fate of the astronauts: Did they die instantly? Or were they conscious of their fate? Now, that mystery may be solved, WESH 2 News space specialist Dan Billow reported. NASA now knows that the astronauts lived through the explosion and tried desperately to survive. Story Musgrave, NASAs most experienced astronaut, said positively that the crew survived the entire way down. That knowledge will change the way future spacecrafts are built. After the Challenger broke apart over the Space Coast on Jan. 28, 1986, the crew compartment fell away intact and tumbled for two minutes until it hit the ocean at a speed of 200 mph. Musgrave, who knows as much about spaceflight as anyone alive, said the astronauts were conscious during those two minutes. Challengers fast, launch is fast, Musgrave said. Its bang and then its a two-minute ride down. And youre conscious. We know that. Musgrave flew on the space shuttle six times, both before and after Challenger. Hes a medical doctor, and space rescue and survival were among his specialties in his 30 years wearing the blue jumpsuit.You died when you hit the water, we know that, he said. Theres nothing controversial about that. No. Its hard evidence. You died when you hit the water. The hard evidence came from the post-accident investigation. A NASA video described the shuttles breakup with clinical detachment, and showed it was not an explosion. The initial path of the crew cabin from the vapor cloud carried it across the path of an adjacent contrail. After 10 seconds, the crew cabin was seen again with the front end and top of the cabin visible, said NASAs Greg Katnik. A NASA statement released after the accident said, The forces to which the crew were exposed during orbiter breakup were probably not sufficient to cause death or serious injury. Some authorities have suggested that a parachute system built into the crew cabin could have saved their lives. At the bottom of the ocean, divers recovered four of the emergency oxygen packs the astronauts had with them. Some oxygen packs were turned on, and investigators say they could not have been turned on by the impact. Someone had to turn them on. Still, NASA has never been willing to make an official conclusion on the fate of the crew. The agency always encouraged the belief that the astronauts blacked out right away NASA is unable to determine positively the cause of death of the Challenger astronauts but has established that it is possible, but not certain, that loss of consciousness did occur in the seconds following the orbiter breakup, the NASA statement said. The only voice recording that came back was the shuttles pilot, Mike Smith, saying uh-oh at the moment of breakup. His was one of the turned-on oxygen packs. Looking at the shuttle disappear into a cloud of fire and vapor, most people probably assume no one could have survived it. Musgrave suggests that NASAs astronauts and other insiders know differently. You could have lost consciousness for a little while at that altitude if it depressurized, but then, no, theres all kinds of evidence that you died when you hit the water, he said. Knowing whether the crew remained conscious after the breakup is important to the survival of future astronauts. The cabin of another shuttle, Columbia, also survived its initial breakup intact, although it did break up later on. Now, a parachute system or other escape method will be built into all future spaceships once the shuttles are retired.
