So, now I am going to answer my main inquiry question, that conducted my research. So my answer starts here.
Aviation has improved because of some of the worst aviation disasters. One was TWA flight 800. On July 17, 1996, TWA flight 800 was going to Rome with a stopover at Paris, carrying 230 passengers. About 12 minutes after takeoff, at 8:31 eastern time, the plane blew up, and shot down to the Atlantic ocean in many pieces. All of the people and crew on board, 230, died. But what was learned was that this should never happen again. Boeing, the plane-maker, developed stronger tanks and better fuel.
Another disaster was United airlines flight 232. On July 1, 1989, UA 232’s engine fan disk imploded, shutting off all of the hydraulic lines. Then, the crew tried to land at Sioux City airport, but the plane failed to touch down properly and it blew up.
