Executive Summary
This Report attempts to unfold the management flaws and terrible decision making that marked the morning of the 28th of January 1986 as a terribly tragic disaster. What it sadder is that this disaster was mainly due to inhumane practices conducted by the NASA and the management bodies of companies associated with this project than natural reasons. The whistleblowing led to the loss of billions of dollars and more importantly loss of 7 innocent lives. The space shuttle was propelled by the two attached Solid Rocket Boosters (SRBs) and an external fuel tank. The SRBs were joined to the External Tank. aOnce the SRBs ignited, hot gases heated the rubber O rings and they eroded to seal the joints. SRB joint design had a serious flaw in it and the engineers knew it meant a catastrophe and yet they passed the design for flight. The O rings worked only down to a temperature limit of 12 ̊ C, but the morning of the launch saw temperatures as low as -1 ̊ C which was much lower than the prescribed limit. Many engineers voiced to postpone the launch and wait for the weather to be stable but the management turned down these arguments and the challenger was cleared to launch at 11:38 A.M. As the shuttle took off, the right SRB emitted puffs of smoke which meant that a gap was punched into the SRB and hot gases were escaping it. The O ring was supposed to seal the gap off but it was frozen so it failed and the secondary O ring was displaced because the casing of the SRB bent away. At about 60 seconds from take off, the smoke became a flame and damaged the external tank and 73 seconds from launch, the shuttle exploded and disintegrated over the Atlantic Ocean killing all the 7 crew members.

Introduction
11:39 am, 28th of January was the disgrace moment for all American and for NASA. On this date six astronauts with a school teacher in a space shuttle named as challenger exploded in a mid-air in front of their families and live televisions. This is first time when an NASA sends average American to the space so she can teach the lesson from the space. This mission seems very safe that’s why the NASA allows an ordinary American to visit international space shuttle. The challenger taking more than 3 billion dollars of equipment and highly trained astronauts but the space shuttle challenger disaster occurred in just 73 seconds from lift-off. Due to live broadcast and public interest, the challenger publicized all over the America. Reason or Mechanical Problems

The main reason of the challenger disaster was the SRB which stands for solid rocket booster. It is a part of the shuttle that helps in lift-off. It also carries the rocket fuel and essentially powers that help shuttle towards outer space. The solid rocket booster exhausts the gasses towards earth, so that rocket moved upward. After lift-off and reaching into mid-air the solid rocket booster normally disconnected from the space shuttle and parachutes towards the earth which can be used for further launches. Solid rocket booster in the shape of cylinder. These cylinders combined with joint and protected by O-ring. These joint normally assemble in Kennedy Space centre. These O-ring made of elastic that used to expand to fill up the gaps in the joint, which can protect the space shuttle from very extreme gasses. In Challenger O-ring is supposed to seal those gaps which were not happen that day. In the result the extreme gasses leak from these gaps. So the holes which normally protected from the seal from the high...
