Jan Schiere Sr.

As the first aeronautical Engineer in the Netherlands he graduated in July 1911 in France at the Ecole Supérieure d'Aérononautique Contruction et de Mecanique in Paris. He has let his parents know via the following telegram.

The wooden propellers were made of Mahony because this type of wood will not splinter when you shoot accidentally a bullet through it. This, because they shot through the rotating propellor.

After World War I, the demand for propellers was much less and the propeller factories had all an expensive stock of Mahony wood. This stock was thus significantly lowered in value. Additionally Ebora also got an extra tax because they had earned on the war.
