Avro's Chief Designer Roy Chadwick first sketched out the innovative delta-winged configuration of the Vulcan over 60 years ago in 1946, just five years after the first flight of his other famous creation, the Avro Lancaster. Sadly he died in a plane crash the following year, and never saw his second masterpiece fly. His work was picked up by Stuart Davies, who took Chadwick's ideas on to fruition.
The prototype full-scale Avro Vulcan VX770 first flew on 30th August 1952, and spectacularly appeared in public at the Farnborough Airshow just a few days later. This picture is from the 1953 Farnborough airshow, and shows VX770 leading the four 1/3 scale Avro 707 research aircraft & the 2nd prototype VX707.
Here is an advertisement for A V Roe Limited from the early 1950s, extolling British leadership in aircraft design and manufacturing, as exemplified by the Avro Vulcan.
