Foundry workers pouring molten metal into an ingot

Ingot making. Two foundry workers pouring molten metal from a furnace into an ingot mould. The metal, titanium, is added to alloys for medical implants and aircraft as it is strong, light and unreactive. The metal is moulded into ingots for ease of transport. The foundry workers clothing is designed to protect them from the heat. Their aprons, arms and visors are silvered because this colour is especially good at reflecting heat

A Canberra aircraft flying high

The original Canberra design dates from the 1940's and the prototype aircraft flew for the first time from Warton aerodrome on 13 May 1949.
The type first entered operational service with the RAF in 1951 as a medium bomber, although photo reconnaissance (PR) variants were first produced soon afterwards.
The prototype PR9 made its maiden flight on 8 July 1955. The aircraft was built under licence by Short Brothers, Belfast and in total, 23 production standard PR9s were built between 1958 and 1962. The first operational sortie was flown by an aircraft of No 58 Squadron in April 1960. The remaining PR9s serve with No 39 Squadron at RAF Marham
