Britannia turboprop airliner on airport tarmac with passengers boarding via stairs, 1950s black and white photograph

A Bristol Britannia turboprop aircraft operated by an unnamed airline sits on the tarmac with passengers boarding via mobile stairs. This photograph from the 1950s captures the era when Britannia aircraft were prominent in British commercial aviation, representing the transition period between piston and jet aircraft that would have been familiar to Sir Freddie Laker during his early aviation career.
