In April 15, 1912, RMS Titanic sank into the ocean after colliding with an iceberg. Why wasn’t the massive iceberg seen? Because the lookouts did not have binoculars. The binoculars were reportedly locked up in a locker, the keys to which were held by David Blair, who forgot to hand them over after he was removed from the ship’s crew the night before the ship’s departure. The binoculars were put up for auction in 2007 and sold for $148,000.
