Vickers Type 170 Vanguard

https://en.wikipedia.org/wiki/Vickers_Type_170_Vanguard

The Vickers Vanguard was a 1920s British airliner developed by Vickers Limited
from the Victoria.

Developed from the earlier Victoria with the introduction of a wider fuselage,
the Vanguard was a 22-passenger twin-engined biplane. Originally built for the
Air Ministry as the Type 62 the aircraft powered by two 450 hp Napier Lion
engines first flew on 18 July 1923. It was re-engined in 1925 with two 650 hp
Rolls-Royce Condor IIIs and re-designated the Type 103. When it was handed over
to Imperial Airways in 1925 it was described as the World's largest passenger
aeroplane.

The aircraft was re-conditioned in 1928 and re-designated the Type 170 for use
by Imperial Airways for route proving trials, starting in May 1928. Ii operated
on the London-Paris route, typically taking about 2½ hrs, and then on the London
Brussels-Cologne service. It set a world load carrying record on 6 July 1928.
The aircraft was withdrawn from its airline duties in October 1928 for
modifications, probably to the tail, but crashed at Shepperton, Middlesex on 16
May 1929 at the start of flying trials, killing the pilot Tiny Scholefield and
the flight observer Frank Sharrett.
