The search for Sir John Franklin refers to the efforts made to locate the British explorer and his crew, who disappeared in 1845 while attempting to navigate the Northwest Passage. Franklin's expedition aimed to chart the Arctic waters, but after failing to return, multiple search missions were launched over the following decades. These searches involved various explorers and ships, including the famous expeditions led by James Fitzjames and Henry Kellett. In 2014, the wreck of one of Franklin's ships, the HMS Erebus, was discovered near King William Island, providing valuable insights into the expedition's fate and the harsh conditions faced by the crew.
