Disasters in Space FlightOn January 27, 1967, the three astronauts of the Apollo 4, were doing atest countdown on the launch pad. Gus Grissom was in charge. His junto wereEdward H. White, the first American to walk in space, and Roger B. Chaffee, anaval officer going up for the first cartridge clip. 182 feet below, R.C.A technicianGary Propst was seated in front of a bank of television monitors, listening tothe crew radio product line and watching various televisions for important activity.Inside the Apollo 4 there was a metal door with a sharp edge. Each timethe door was dependent and shut, it scraped against an environmental control unitwire. The repeated abrasion had exposed two tiny sections of wire. A sparkalone would not perplex a fire, except just below the cuts in the cable was a lengthof aluminum tubing, which took a ninety-degree turn. on that point were hundreds ofthese turns in the whole enclose. The aluminum tubing carried a dihydric alcohol coolingflui d, which is not flammable, however when exposed to air it turns to flammablefumes. The capsule was filled with pure oxygen in an effort to throw overboard theastronauts to work more efficiently. It also turns normally not so flammableitems to highly flammable items. Raschel netting that was highly flammable inthe pure oxygen environment was border on the exposed section of the wires.At 63104 p.m. the Raschel netting burst into an open flame. A secondafter the netting burst into flames, the first communicate came over the crewsradio channel Fire, Grissom said. Two Seconds later, Chaffee said clearly,Weve got a fire in the cockpit. His tone was businesslike (Murray 191).There was no camera in the cabin, but a remote control camera, if zoomedin on the porthole could provide a partial, shadowy view of the interior of thespace craft. There was a address of motion, Propst explained, as White seemed tofumble with something and then quickly pull his blazon back, then reach ou t again. Another pair of arms came into view from the left, Grissoms, as the flamesspread from the far left-hand corner of the spacecraft toward the porthole(Murray 192). The crew struggled for about 30 seconds after their suits failed,and then died of asphyxiation, not the heat. To guide out of the capsuleastronauts had to remove three separate hatches, atleast 90 seconds was requiredto open all three hatches.Disasters in Space Flight Essays PapersDisasters in Space FlightOn January 27, 1967, the three astronauts of the Apollo 4, were doing atest countdown on the launch pad.

The aluminum tubing carried a glycol coolingfluid, which is not flammable, but when exposed to air it turns to flammablefumes. The capsule was filled with pure oxygen in an effort to allow theastronauts to work more efficiently. It also turns normally not so flammableitems to highly flammable items. Raschel netting that was highly flammable inthe pure oxygen environment was near the exposed section of the wires.At 63104 p.m. the Raschel netting burst into an open flame.
