People kneel down to see "the Sahara Mirage" created by the heat wave in London.
Item title reads - Seeing Things! Crowds kneel and gaze for hours at London's heat wave novelty - "the Sahara Mirage". The Mall, London.
We see people crouching down looking at something and getting up afterwards, traffic drives past in the background. Various shots as people kneel down, and look through an arch where cars drive through and create lots of dust.
