I remember the filming of that whole sequence for "The Hot Rock" (I lived two blocks away). It took about 3 or 4 nights to put the scene together on film. The night the car exploded, the pigeons who slept in the Brooklyn Museum's facade were asleep, then the car went boom and all of a sudden it was raining pigeon s@*t. One of 132's lieutenants was trying to convince someone from the film crew that local firemen not extras from out of the neighborhood should represent the FDNY in the film. He was unsuccessful.
