LONDON (AP) -- Passengers arriving and departing from London's Heathrow airport faced delays and cancellations Wednesday when both the airport's runways were blocked.
Heathrow's southern runway was blocked when the brakes on a KLM Boeing 767 aircraft jammed at 1:15 p.m. (1215GMT).
Departures were switched to the northern runway, but it was also blocked when a Cathay Pacific aircraft departing for Hong Kong suffered overheating breaks at 2:30 p.m. (1330GMT).
Airport authority BAA said the northern runway reopened within nine minutes. The southern runway was closed for three hours.
''There are delays occurring to both departures and arrivals as Heathrow returns to normal,'' BAA said in a statement.
