Westland Dreadnought

Only a single aircraft was built, and it crashed on its initial flight, badly injuring the test pilot.

[1] The Dreadnought was distinct for its futuristic design and method of construction, based on the theories of the Russian inventor N. Woyevodsky.

[1][2] On completion of the Dreadnought, the pilot Arthur Keep carried out taxi trials and short airborne hops.

The aircraft was initially stable, it soon became clear that Keep was losing control and not long after, at a height of about 100 ft (30 m), the Dreadnought stalled and crashed.

[5] After this failure, the Dreadnought design was abandoned, although the ideas that were conceived and used in its making were visibly an advancement in aircraft and are appreciated as such in the present day.
