Philadelphia Apparatus Crash Two firemen were killed and ten persons were injured as the result of a collision between two fire trucks in the mid city section of Philadelphia. The accident occurred when the Rescue Squad wagon, speeding east, plowed into the side of a combination hose and chemical truck going north. Ladder Truck 23, which was following the Rescue Squad from the Fire Headquarters. was stopped in time to avoid striking the wrecked apparatus. The driver and a member of the Rescue Squad crew were killed, while the others riding the apparatus were injured when thrown to the street by the impact. The fire to which they were responding. a box alarm from Fifth and Callowhill Streets, did only two dollars damage, as the wiring system of an automobile short-circuited.
