The Bristol M.1 Monoplane Scout was a British monoplane fighter of the First
World War.
In 1916, Frank Barnwell, chief designer of Bristol Aeroplane Company, realising
that the performance of existing fighter aircraft was inadequate, designed a new
single-seat tractor monoplane fighter as a private venture, the Bristol M.1.
The first prototype, the M.1A made its maiden flight on 14 July 1916. It was of
conventional wood and fabric construction, with a carefully streamlined circular
cross-section fuselage. The wing was shoulder mounted and was braced with flying
wires running from the wing to the lower fuselage and landing wires from the
wings to a cabane made of two semi-circular steel tube hoops positioned over the
pilot's cockpit. A 110 horsepower (82 kW) Clerget rotary engine drove a
two-bladed propeller fitted with a large hemispherical spinner to reduce drag.
It was purchased by the War Office for evaluation, and demonstrated impressive
performance during official testing, reaching a speed of 128 miles per hour (206
km/h) and climbing to 10,000 feet (3,000 m) in 8 minutes 30 seconds, although
the forward and downward view was criticised by test pilots.
km/h) higher than any of the contemporary German Fokker Eindecker and French
Morane-Saulnier N monoplanes - it was rejected by the Air Ministry for service
on the Western Front, ostensibly because its landing speed of 49 mph was
considered too high for small French airfields, but more likely because of a
widespread belief that monoplane aircraft were inherently unsafe in combat. The
RFC had imposed a ban on monoplanes after the crash of one of the Bristol-Coanda
Monoplanes on 10 September 1912.

the rest were used by UK-based training units, where they were popular as
personal mounts for senior officers.
One pilot of the M.1Cs that served on the Macedonian Front was Captain Frederick
Dudley Travers DFC of No. 150 Squadron RAF, the only ace on this type. Travers
switched from the Royal Aircraft Factory SE.5a, in which he had scored three of
his four kills and scored the last five of his victories between 2 and 16
September 1918, possibly all in the M.1C serial number C4976. Amongst his
victims was a Fokker D.VII, widely regarded as the best German fighter of its
day.
Twelve were sent to Chile on second half of 1918 in part payment for the
battleships Almirante Latorre and Almirante Cochrane being built for Chile in
Britain but commandeered for the Royal Navy before completion. One of these,
flown by Lt. Dagoberto Godoy, was used to fly from Santiago to Mendoza,
Argentina and back on 12 December 1918, the first flight across the Andes
mountain chain.
The Lucifer engined M.1D, painted red and registered G-EAVP, was successfully
raced during 1922, winning the handicap prize in the 1922 Aerial Derby, piloted
by L.L. Carter. The next year it was fitted with a specially tuned 140 hp (100
kW) Lucifer and entered for the Grosvenor Cup, during which it is crashed at
Chertsey on approach to Croydon Airport, killing the pilot, Ernest Leslie Foot.
