the growing European market. Disappearance On the evening of 4 July 1928, Loewenstein left from Croydon Airport to fly to Brussels on his private aircraft, a Fokker F.VIIa/3m trimotor (G-EBYI), along with six other people. While the aircraft was crossing the English Channel at an altitude of , Loewenstein went to the rear of the aircraft to use the lavatory. In Loewenstein's aircraft, a door at the rear of the main passenger cabin opened on to a short passage with two doors: the one on the right led to the lavatory, while the one on the left was the aircraft's entrance door. When Loewenstein had not reappeared after some time, his secretary went in search of him and discovered that the lavatory was empty, while the aircraft's entrance door was open and flapping in the slipstream. The employee (along with the others on the aircraft) asserted his belief that Loewenstein had fallen through the aircraft's rear door and plunged several thousand feet to his death in the English Channel.

On 12 July 1928, it was reported that tests had been conducted by the Accidents Branch of the British Air Ministry using Loewenstein's aircraft. It was stated that at an altitude of one of the Ministry men had thrown himself against the aircraft's entry door, which had opened about . However, he was immediately thrown back into the aircraft when the slipstream violently slammed the door shut. It was concluded that it would have been impossible for someone to accidentally open the door and fall out. Loewenstein's body was discovered near Boulogne on 19 July 1928 and was taken by fishing boat to Calais, where his identity was confirmed by means of his wristwatch; an autopsy was performed (at the request of his family), his brother-in-law stating that they did not suspect anyone of foul play, but that they did not want anyone to suggest after the burial that Loewenstein might have been poisoned or had died in the aircraft and then been thrown out. The autopsy revealed a partial fracture of Loewenstein's skull and several broken bones; it was concluded that he had been alive when he struck
