the water. Loewenstein was buried in a cemetery outside Evere, in a tomb belonging to his wife's family, the Misonnes. However, his name was never carved on the slab covering his casket, so he was in effect buried in an unmarked grave. Theories Many theories have been put forward as to exactly what had happened to Loewenstein in the back of his aircraft; some suspected a criminal conspiracy in which his employees murdered him. The New York Times hypothesised that a growing absent-mindedness, noted by many of Loewenstein's acquaintances, may have caused him to walk out the wrong door of the aircraft. Because he had left behind a tangled web of business ventures, many of which were highly leveraged, others theorized that his business empire was on the verge of collapse. Some even asserted that corrupt business practices were about to be exposed and that Loewenstein, therefore, committed suicide. None of these theories were ever proven. In 1987, William Norris wrote Loewenstein's story in a book titled The Man Who Fell From the Sky (New York: Viking, 1987). Norris presents evidence in support of his case that, if Loewenstein's death was not a conspiracy by business rivals and associates, a certain opportunism existed regarding the death of the tycoon and his insurance. He also shows that later events are frequently ignored, such as the fact that Loewenstein's son Robert shot one of the family servants under murky circumstances within a decade or so after the tragedy. The son was himself killed in an aviation accident in 1941 while serving with the Air Transport Auxiliary. Norris concluded that Loewenstein had been thrown from the aircraft by the pilot, Donald Drew, at the behest of Madeleine Loewenstein, the motive being to gain control of his fortune. He suggested that the aircraft's rear door was completely removed while in the air, and a replacement later fitted on the beach at St. Pol. Crime writers Robert and Carol Bridgestock have speculated that Loewenstein faked his own death and disappeared because of the financial irregularities in his businesses. This theory is supported by the facts that the body was buried in an unmarked grave, and that his wife did not attend the funeral. In popular culture In 2010, Loewenstein's death was the subject of an episode of the History Channel's Vanishings! series. In 2014, Loewenstein's death was the subject of an episode of BBC Radio
