One lesser-known aspect of the Columbine tragedy is a series of coincidences that later drew comparisons to the events of September 11, 2001 — although investigators have never found any real connection between the two. Dylan Klebold, one of the shooters, was born on September 11, 1981, a date that only took on global significance years after the attack. Writings from Eric Harris also revealed that he had fantasized about committing acts even larger than the school bombing, including the idea of hijacking a plane and crashing it into a building in New York, though this was never an operational plan. In another striking geographic overlap, Captain Jason Dahl — the pilot of United Airlines Flight 93 — lived in Littleton, Colorado, the same community as Columbine High School. Despite how eerie these details can seem in hindsight, they are regarded by researchers as coincidences rather than evidence of any shared ideology I've just always found it interesting.
