The plan was to take the plane to Belgium, where Loewenstein was a citizen.
While the plane was flying over the English channel, Loewenstein got up and went to the bathroom.
After entering the bathroom, Loewenstein was never seen alive again.

When his assistant went to check on Loewenstein, they found the planes bathroom empty.
The external door was open.
The assistant notified the pilot who decided to land the plane on a beach outside of Dunkirk.
The crew believed Loewenstein had accidentally fallen out the door and into the English Channel.
On July 19, Loewensteins body was found floating in the Channel.
They reported the door could not have been opened by accident.
Others argue that the entire thing was faked and that Alfred Loewenstein never died that day.
