A giant fatberg stretching the length of about 700 suitcases lined up end to end has been found near Heathrow airport. The wall of congealed fat, which measured 1,640ft, was stuck inside a sewer in Slough, Berkshire, near the airport’s Terminal 5. Thames Water said the discovery was a clear reminder that things put down the drain don't "simply disappear".
