The thing that really did it was, this guy just didn’t pass it on…That’s what caused the disaster … It’s like everything else in the world: Somebody just simply screwed up.” Arnold young, lawyer for hunterMaClean Thiokol Memorial Project’s Thiokol Memorial Museum in downtown Kingsland. (Laura Corley/The Current) Testifying before the Presidential Commission on the Space Shuttle Challenger Accident, also known as the Rogers Commission, McDonald's account revealed the coverup. [12] According to Michael J. Neufeld, The curing agents most commonly used are oxygen donating materials such as manganese dioxide, calcium peroxide, cumenehydroperoxide, and p-quinonedioxime. Lower valence metallic oxides, other organic hydroperoxides, metallic paint driers, and aldehydescan also function as curatives. Oil, Solvent, and Chemical Resistance Cured THIOKOL® LP has excellent resistance to a wide number of oils and solvents including aliphatic and aromatic hydrocarbons, esters, ketones, dilute acids and alkalies. Aging and Weather Resistance Cured THIOKOL® LP has excellent resistance to aging, ozone, oxidation,

In 1975, Thiokol succeeded Sperry Rand as operator of the large Louisiana Army Ammunition Plant near Minden, Louisiana. Fogle had worked the night shift at Building M-132, and was at home at the time of the explosion. The scenes of the aftermath she described witnessing were akin to a soldier’s trek across a battlefield.What Thiokol told its employees is what the U.S. Army had told the company: The magnesium trip flares contained a Class 2 explosive, a flammable material. Only later, when the factory had been reduced to cinders, did it become known that the army had failed to inform the company that the material had been upgraded to a Class 7 explosive, the most dangerous classification. The classifications determine how the materials are handled and stored. He says the same thing today, sitting in a big easy chair in the same living room, his eyes watery and his face grave. The data he and his fellow engineers presented, and their persistent and sometimes angry arguments, weren't enough to sway Thiokol managers and NASA officials. Ebeling concludes he was inadequate. He didn't argue the data well enough. Many victims and their families were so consumed by grief and trauma they were unable to manage their daily lives. Neither the company, nor any other government agency, offered the Woodbine families any counseling.

It was kind of eerie,” she said. “It was scary, because after that you best not even drop a pin on the floor because everybody would go run.” Fires and evacuations were so routine at Thiokol, that when a small flame was spotted on the assembly line in Building M-132 shortly before 11 a.m. on Feb. 3, 1971, many employees on the factory’s morning shift left their stations, but didn’t move very far away from the building.

OUTSTANDING BATTERY DURABILITY Industrial tablet PC with the integrated polymer li-ion battery, 3.7V/12600mAh, the rugged touchscreen tablet could withstand 8-hour use. The low power design allows long time of field work, without worrying about data lossing in the field. An essential production tool to get jobs done, ideal for enterprise mobile work.
