In this day and age, it is not uncommon to hear about tragic plane crashes. It is an unfortunate reality that goes hand-in-hand with not only machinery like planes, but boats and cars as well. When one of these tragedies hits close to home, however, it is etched in your brain forever, like this terrifying Colorado plane crash that will never be forgotten:
On March 3, 1991, United Airlines Flight 585 was scheduled to fly from Denver to Colorado Springs with 20 passengers and five crew members on board.
Before landing at Denver's now-closed Stapleton Airport (pictured), the United flight flew without incident from General Wayne A. Downing Peoria International Airport in Peoria, Illinois to Quad City International Airport in Moline, Illinois, making all of its scheduled stops on time.
During the flight's descent into the Colorado Springs Municipal Airport (pictured), the Boeing 737-291 rolled to the right and pitched nose down, which the pilots tried to correct whilst the plane lost altitude and gained speed.
For nearly two years, the National Transportation Safety Board sought answers for what could have gone so terribly wrong, later stating "The National Transportation Safety Board, after an exhaustive investigation effort, could not identify conclusive evidence to explain the loss of United Airlines flight 585."
It wasn't until 10 years later when the case was reopened due to similar crashes, which is when the NTSB determined that the pilots lost control of the airplane due to a mechanical malfunction.
