On this date in 1979, American Airlines flight 191 crashed just outside of O’Hare International Airport killing 273 people.

This is still single worst non terrorist related aircraft crash in the history of the United States. The Chicago Fire Department, along with various suburban departments responded to the scene and all participating agencies conducted themselves to the best of their abilities.

Today we remember those who passed and pay tribute to those who responded. We will always remember Flight 191. Happy Memorial Day tomorrow.
