This from Steve Redick:

Thanks again to Kevin Kirkley for sharing this one with us. The audio starts at the 3-11 and as many times as we may all have heard this, it is interesting … Anyone know the real story behind “no not fog-pressure but high-pressure”  ??

Also notice the famous send everybody available request?  This was Mayor Daley’s palace and Commissioner Quinn was really on the spot.

From Wikipedia:

The 1960 exposition hall was destroyed in a spectacular 1967 fire, despite being thought fireproof by virtue of its steel and concrete construction. At the time of the fire, the building contained highly combustible exhibits, several hydrants were shut off, and there were no sprinklers on the main floor where the fire started. Thus the fire spread quickly and destructively, taking the life of a security guard.^[4] The fire was investigated by a team led by Rolf H. Jensen, Professor of Fire Protection Engineering at the Illinois Institute of Technology, who later went on to found RJA Group. Many lessons were learned and the city’s building code was amended so a similar situation would not be repeated. Although many wanted to rebuild the hall on a different site, Chicago mayor Richard J. Daley elected to rebuild on the foundations of the burned building. The new design of dark steel and glass, by Gene Summers of C. F. Murphy and Associates (and formerly of Mies van der Rohe‘s office) contrasted markedly with the white look of the structure that had burned down. On January 3, 1971, the replacement building, later called the East Building and now called the Lakeside Center, opened with a 300,000 square feet (28,000 m²) main exhibition hall.
