In October 1937, Georg Donatus's father,
Grand Duke Ernest Louis of Hesse, died. A few weeks after the funeral, his younger brother,
Prince Louis, was due to marry the Hon. Margaret Geddes, daughter of
Lord Geddes. On 16 November 1937, Georg Donatus, Cecilie, their two young sons, Georg Donatus's mother, Grand Duchess Eleonore, the children's nurse, a family friend, a pilot, and two crewmen took off in a
Sabena Junkers Ju 52 aeroplane from Darmstadt, bound for the
United Kingdom, where Louis's marriage ceremony was to take place. The aeroplane struck a factory chimney near
Ostend, in
Belgium, and
crashed, bursting into flames and killing everyone on board. Cecilie was in an advanced state of pregnancy with their fourth child at the time of the crash. The remains of the newborn baby were found in the wreckage, indicating that Cecilie had gone into
labour during the flight. The inquiry by the Belgian authorities suggested that, because of the birth, the pilot had attempted to land at the
Stene aerodrome in Ostend despite poor weather conditions. ==Aftermath==
