From OIC member Staffan Westerberg:
Ralph, I have been interested in the role of the Dallas Fire Department on November 22. I did find an image of one firetruck on the scene. If my memory is correct, either Curry or Fritz called the DFD to come and "help out" at the TSBD. That was around 12:45, and they (the firemen) all stormed in and through the building up to the roof. But, nobody has ever explained why they were needed. The entire DPD was on the scene in one minute!
