At the time, the press compared his likely fate to that of Cecil Grace and Edouard Jean Bague, who disappeared during flights over water (in December 1910 and June 1911 respectively).
[4] Jewell held a pilot's licence issued by the Aero Club of America; at the time of his disappearance, he had been flying for six months and he was an instructor at the Moisant Aviation School, though he had little experience of flights of the distance he was attempting.
[1][5] His last flight was planned to be from the Moisant Aviation School near Hempstead, Long Island to the Oakwood airfield from which the competitors in the race were due to depart.
[10] As Jewell was unable to swim and his only flotation device was the inner tube of a tyre, his chances of surviving a ditching at sea were poor, even if he managed to get clear of the wreckage of his aircraft.
Several rewards were offered for information which might reveal what accident had befallen Jewell and the location of his remains; $400 by the Aeronautical Society; $300 by the aviator's widow and $250 by the Moisant Aeroplane Company.
