Design and development
After the failure of his first aircraft design Geoffrey de Havilland began construction of his second aircraft, re-using the engine that he had designed for the earlier machine.

s mounted on the upper wing. De Havilland and several other pilots flew it at Farnborough until it crashed in the summer of 1911 while piloted by Lt. Theodore J. Ridge, who was later killed flying the S.E.1.
"Rebuild" as the F.E.2
The crashed F.E.1 was "rebuilt" in August 1911 as the F.E.2. In fact it was a "rebuild" in name only, as it was a completely new design, incorporating few if any actual components of the original (at this stage Farnborough were still not authorised to build aircraft from scratch). The Iris engine, seriously damaged in the F.E.1 crash, was replaced by a 50 hp.

In 1913 the F.E.2 design was once more heavily reworked with a new and streamlined nacelle, upper wing panels which extended the span to 42 ft (12.08 m) and a revised tail with a smaller rudder and tailplane lifted to the top

s. The nacelle was by now deeper and more spacious, while the mainplanes were identical to those of the B.E.2a. The Gnome was replaced by a 70 hp (52 kW) air cooled Renault V-8 engine. Effectively, although the factory now routinely constructed original aircraft, it was another case of a new design reusing the designation of an older one. It was lost in a crash near Wittering on 23 February 1914 when the pilot, R. Kemp lost control while in a dive, Kemp being unable to recover from the "steep spiral descent", killing his passenger. The rebuilt design had not had sufficient fin area to balance the area of the nacelle side.''Flight'' p724,
