Handley Page Type B
The Handley Page Type B was an unusual single-engined pusher biplane built by Handley Page at the commission of a Liverpool patent agent. Damaged before its first flight, Handley Page disowned it, but it was rebuilt and flew for a time in 1910 ...

Robert C Fenwick
Robert Cooke Fenwick (6 October 1882—13 August 1912) was a British aircraft pioneer and designer.
Fenwick was educated at South Shields High School between 1893 and 1895, leaving the school to go to school in Jersey.
After school, he became ...
. Early testing of the Type B proved unsuccessful, and Handley Page abandoned the aircraft unflown. After further modification by Fenwick at Planes Limited's works at
Freshfield, Formby, the aircraft flew successfully in November 1910.

Fenwick and Sydney T Swabey designed a second aircraft for Planes Limited in 1911, this being a single-engined pusher

, which was mounted in the aircraft's nose, driving a two-bladed propeller by a long extension shaft. The pilot and passenger sat side-by side in the fuselage nacelle, which was mounted below the aircraft's wing, with the propeller shaft passing between them. The tail surfaces were carried on two steel tube booms, while the aircraft's undercarriage consisted of two mainwheels and long skids designed to prevent the aircraft turning over onto its nose in the event of a rough landing.
[Bruce 1982, pp. 31–32.][''Flight'' 17 August 1912, pp. 755–756.]

The monoplane first flew in late 1911.
In April 1912, Fenwick and Swabey set up their own company, The Mersey Aeroplane Company, purchasing the monoplane from Planes Limited and continuing to operate from their works at Freshfield. It was flown frequently in the spring of 1912, often carrying passengers, including the 70-year-old Thompson, who was believed to be the oldest person to have flown at that time.
[''Flight'' 18 May 1912, p. 448.]
The monoplane crashed in the summer of 1912, but was rebuilt by Fenwick with the intent of entering it into the
Military Trials which were to take place in August that year. The rebuilt aircraft had longer-span wings, larger tail surfaces and shorter tail booms, but retained the Isaacson radial engine.
The rebuilt aircraft flew successfully at Larkhill as part of the trials on 9 and 11 August, but when carrying out a third flight on 13 August in gusty weather conditions, dived into the ground from a height of about 200 feet (60 metres), killing Fenwick.
[''Flight'' 17 August 1912, p. 756.] The accident was investigated by the
Royal Aero Club
The Royal Aero Club (RAeC) is the national co-ordinating body for air sport in the United Kingdom. It was founded in 1901 as the Aero Club of Great Britain, being granted the title of the "Royal Aero Club" in 1910.
