The airport has been in operation for 65 years. Not only a general aviation airport (a very busy one, at that), but also some small-package cargo operation flows through it as well.
Although 4 previous instances of airplane accidents have occurred (1986, 1992, 2004, 2011) after flights took off from Addison Airport, no flights until Sunday actually crashed at the airport. A Beechcraft plane crashed into a hangar at the airport as it was attempting to take off. All 10 aboard died.
