Electric Boat shipyard, Groton, 21 January 1954: bolted steel sponsor platform beside the bow, grease-darkened timber launching ways, welded shipyard structure, and the riverward descent continuing beyond the tight frame. Mamie's shoes contact the timber platform deck; her left forearm contacts the rail and her right leather glove closes fully around the bottle neck. The platform terminates beside the bow at sponsor height, giving the bottle a clear swing path to the steel contact point. The bottle's fractured lower body touches the bow; every droplet and retained shard originates at that single contact point. The safety wrapping remains around the bottle and physically contains the larger glass fragments as gravity draws liquid and small fragments downward. The wet patch lies directly below the bottle impact, conforming to the bow's curved steel surface. The lower hull rests continuously on the cradle's padded bearers; wedge blocks contact adjacent cradle members. Both cradle runners contact the two greased ways, which support the submarine and descend toward the river. Mamie, bottle, splash, bow, cradle, and ways cast soft shadows consistently toward lower-right. Nautilus's 8.4 m maximum beam is about five times a roughly 1.6 m human figure; the cropped bow preserves that proportional scale.
