This invention greatly simplifies problem fires above the reach of the longest ladder trucks by using a telescoping, portable shaft extending out of the closest window opening below the fire. Normally, a safe place for firemen. On the outer end of the shaft is a servo-mechanically controlled fire hose nozzle with a miniature television camera, which then both connect along the shaft to the room the shaft extends from. From where firemen can direct water using a console containing a television screen and battery power for the system. Stored in sections aboard its own truck in areas with high buildings, sections which are each, separately, carried up using the stairs by individual firemen, ordinarily the three man crew of a companion ladder fire truck. This invention now allows serious fires in high-rise buildings to be safely and effectively controlled.
