Heathrow’s nine runways

When was a third runway for Heathrow first proposed? Heathrow was always planned to have multiple runways. On 10 April 1946, before the airport was even open, the Minister for Civil Aviation, Lord Winster, announced that the then London Airport was to have nine runways. Six would be in a Star of David pattern on the present site of Heathrow; the other three would form a triangle to the north of Bath Road, where the current proposal for a third runway is based.
