Comet 2 and the RAF

Comet Mk.2s were operated by the RAF – mostly in Transport Command but also in various modified forms.

Comet 3

When it was decide that the Comet 2 would not enter airline service a much bigger Comet was designed. The Comet 3 became a test bed for development of the Comet 4 and 4B


A series of tragic accidents grounded the Comet 1 – as aircraft manufacturers discovered the concept of metal fatigue.

Court of Inquiry

A Court of Inquiry was set up to determine why a number of Comet Mk.1s crashed.

BOAC Comet 1s

BOAC became the main and as it happened only operators of the Comet 1

Comets Mk.4, 4B, 4C and C4

Moscow Trip

In 1956 the Soviet Union was planning a prestigious Air Show. An official invitation was extended by the Soviet leader – Nikita Kruschov – via their head of Aviation (Bulganin), to the British Secretary of State for Air, Nigel Birch, to visit Moscow that June to see the Soviet Air Show at Tushino airfield, Moscow.
This is an account of that visit ….

The Blériot AIR RACE

In 1909 Lord Northcliffe offered a prize to the first aviator to fly across the English Channel.Fifty years later, in July 1959, the Daily Mail newspaper sponsored a celebratory Air Race as a tribute to Louis Blériot and offered a prize of £10,000.
BEA entered a team known as the BEAline syndicate – see how they got on…

Flight Engineer's Logs XA-NAR

Aircraft, particularly new types of aircraft, have to undergo a thorough testing and evaluation procedure before entering service The trials of G-AOVU are typical of that process.
Here we have logs from the first flight on 31st Oct 1959 up until 9th Aug 1962 with a scheduled flight from Mexico Cioty to LA.
