Introduction

This paper is going to compare the Apollo 1 and the Challenger disasters. two space

programs were unfortunate disasters, caused by a series of oversights and misjudgments.

        On January 27, 1967, the three astronauts of the Apollo 4, were doing a test

countdown on the absorb pad. Gus Grissom was in charge. His crew were Edward H.

White, the first American to walk in space, and Roger B. Chaffee, a naval officer going up

        Inside the Apollo 4 in that respect was a metal door with a sharp edge. severally time the door

abrasion had open two tiny offices of wire. A spark alone would not cause a fire, but

just below the cuts in the cable was a length of aluminum tubing, which took a ninety-

degree turn. There were hundreds of these turns in the exclusively capsule. The aluminum

tubing carried a glycol cooling fluid, which is not flammable, but when undecided to air it

turns to flammable fumes.



The capsule was filled with pure type O in an effort to allow

the astronauts to work more efficiently. It also turns normally not so flammable items to

exceedingly flammable items. Raschel netting that was highly flammable in the pure oxygen

environment was near the exposed section of the wires.

        At 6:31:04 p.m. the Raschel netting burst into an open flame. A second after the

netting burst into flames, the first pith came over the crews radio channel:...
