Deep Sea Detectives. This became the deepest wreck dived of the 56 episodes made. The wreck now lies resting on her port side in a depth of on the seabed of the western approaches to the English Channel. Leigh Bishop recovered artifacts from the site, which went on display for many years to the general public in the Cornish Maritime Museum. Speculation into the sinking and cargo Speculations about a shipment of zirconium, intended for use in the first nuclear submarine USS Nautilus (SSN-571), but registered as pig iron, were discussed in a 2002 Danish television documentary Det Skæve skib (English title: The Mystery of Flying Enterprise). According to this documentary, information regarding the cargo is still (in the year 2002) regarded as confidential and details are not available from the CIA, FIA, Coast Guard and/or US Navy. On the other hand, there appears to have been no secret that the US Atomic Energy Commission was acquiring zirconium, so it is not clear why any of these organizations should actually have information related to the Flying Enterprise. In the interview with Bekker, Carlsen tells him that yes the ship had a zirconium cargo and that it came from the German nuclear energy project. While there seems to be no reason to doubt the first statement, the origin of the zirconium is questionable as the German nuclear energy program was not very advanced. It has been speculated that the zirconium instead came from Philips in Eindhoven, the company that had the first patent on a process to obtain high purity zirconium, and that the buyer was one of the companies intending to bid for a contract with the US Atomic Energy Commission. Hammond Innes fictionalized the story with "The Wreck of the Mary Deare" published in 1956, about a decrepit and drifting freighter found by a salvager. A movie by the same name was made in 1959 and featured Gary Cooper and Charlton Heston. The plot features a salvager (Heston) boarding a drifting freighter with only the first officer onboard trying to run the ship by himself (Cooper). After the ship is finally caught up on some rocks, the two survive but Cooper has to face a court of inquiry which does not go well. Cooper and Heston then go on to investigate the sunken cargo, supposedly high-quality American aircraft engines. Passengers and cargo The passengers on board Flying Enterprise were
