      p {'On 28 January 1986, the space shuttle Challenger was launched by the National Aeronautics and Space Administration (NASA) from Kennedy Space Centre. NASA is a United States agency responsible for US space research and exploration as well as aeronautics. This mission was named STS-51L. 73 seconds into the flight, the external fuel tank exploded, causing the shuttle to come apart. The crew compartment free-fell for 2 minutes and 45 seconds, ending its descent in the Atlantic Ocean. It hit the water at over 320 km/h, which is most likely what caused the death of all 7 on board.'}

      p {'Allan Mcdonald was a Morton Thiokol employee who was in charge of the Solid Rocket Boosters, and opposed the launch. Morton Thiokol was the company contracted by NASA to make Solid Rocket Boosters. Another important individual was a teacher aboard the Challenger named Christa Mcauliffe, who would have been the first civilian in space. The Teacher in Space Program was announced by Ronald Reagan in 1984. It was meant to honor educators and increase interest in STEM, but resulted in millions of American children watching a manned spacecraft explode live, including Mcauliffe’s own students.'}

Additionally, fluid dynamics experiments were planned to be conducted by Gregory B. Jarvis.'}
