Patrolman Irwin “Irv“ Francis Hayden, Star #4005, aged 52 years, was a 23 year veteran of the Chicago Police Department, assigned to the Bureau of Operational Services - Traffic Division, Special Activities Group: Unit 152 - Public Safety Education Bureau.
On August 10, 1971, at 4:28 p.m., Officer Hayden was on duty aboard the WGN traffic helicopter in his assignment of reporting traffic conditions in the Chicago area. During the flight, his helicopter suffered an airframe failure and lost control. The helicopter was flying at a low altitude of less than 100 feet, and according to witnesses the copter repeatedly dipped and tilted to one side. Just before the crash the helicopter gained altitude and tilted to one side again. The helicopter then crashed into a 70 foot high tension wire utility pole and fell to the ground bursting into flames. The helicopter came down in a little league baseball field located at 900 Cernan Drive, Bellwood, Illinois. Both Officer Hayden and his Pilot David Demarest, age 29, were killed in the crash.
