When American Airlines Flight 191 crashed just north of O'Hare International Airport there were were many witnesses to the smoke and fire that immediately rose from the crash site. Some fire units were already on the street and reported the unknown source of a huge fire and headed straight for the disaster scene.
This video clip includes the audio (with added transcript in video text) of the Local Fire frequency that was shared by several suburbs just north of the airport: Elk Grove Township, Elk Grove Village, Mount Prospect and Arlington Heights.
Abbreviations used in the video transcript:
AHTS ... Arlington Heights Fire Department serves the next suburb north of Elk Grove Village. The Arlington Heights Fire Alarm Office was also the command center for MABAS Division 1 (Mutual Aid Box Alarm System) -- the mutual aid district that encompassed the disaster scene. The Arlington Heights Fire Department office managed the MABAS response via the NIFERN radio frequency, which is now known as IFERN and is used for major disasters when mutual aid among fire departments is required. Chicago Fire Department also managed a separate command that is not heard in this audio.
EGRT ... Elk Grove Township Fire Department is the fire protection district that was closest to the disaster scene, directly north of O'Hare International Airport. At the time of the crash, Elk Grove Township Fire Department was a brand new department. If I remember correctly, their ambulance had not yet certified for Advanced Life Support at the time of the crash. That is probably why EGRT Ambulance 321 was calling for help requesting an MICU. In the early days of Emergency Medical Service (EMS), Advanced Life Support (ALS) ambulances staffed by paramedics were called Mobile Intensive Care Units (MICU).
EGRV -- Elk Grove Village Fire Department was the next closest suburb to the disaster scene. EGRV borders most of the west side of O'Hare International Airport. Most of the dispatcher communication at the beginning of the audio is from the Elk Grove Village Fire Department fire dispatch/alarm office.
MABAS ... Mutual Alarm Box Alarm System invented in 1968 for suburban fire departments and modeled after the City of Chicago fire response alarm system. The system now includes the suburbs and the City of Chicago.
MTPR ... Mount Prospect Fire Department covers the next suburb north of the district covered by Elk Grove Rural Township Fire Department.
NIFERN ... Northern Illinois Fire Emergency Radio Network is former name of IFERN the current acronym for the Interagency Fire Emergency Radio Network.
