The Blower Unfilmed Scene was an unfilmed and deleted scene of Titanic 1997. It remains in the script at http://sites.inka.de/humpty/titanic/script.html SCRIPT:
255 EXT. FORWARD FUNNEL Collapsible A is whirled like a leaf in the currents around the sinking ship. It slams against the side of the forward funnel.
CAL:
(to the crew in the boat) Row! Row you bastards!!
256 NEARBY: Fabrizio is drawn up against the grating of a STOKEHOLD VENT as water pours through it. The force of tons of water roaring down the ship traps him against it, and he is dragged down under the surface as the ship sinks. He struggles to free himself but cannot. Suddenly there is a concussion deep in the bowels of the ship as a furnace explodes and a blast of hot air belches out of the ventilator, ejecting Fabrizio. He surfaces in a roar of foam and keeps swimming.
It was probably deleted for pacing and timing, but it remains in the script.
