Some of the earliest aerial photographs of Britain go online today.

The pictures were taken from 1919 onwards by a pioneering company called Aerofilms.

They are being made available by English Heritage and its equivalents in Scotland and Wales.

Nick Higham went to the English Heritage archive at Swindon to learn more.
