Some flights at London's Gatwick and Heathrow airports have been diverted due to high winds battering much of Britain and western France.
The high winds from Storm Katie caused 87 cancellations and 43 diversions at Gatwick and Heathrow because flights had trouble landing safely.
Passengers tweeted about "scary'' aborted landings and being diverted to other English cities.
Gatwick also reported some problems on the road leading to the North Terminal and both airports advised passengers to check the status of their flights before traveling to the airport.

British police continued to investigate the death Saturday of 7-year-old Summer Grant, who was killed while playing on an inflatable bouncy castle that was swept away by a sudden gust of wind. An autopsy showed she died of multiple injuries after being carried some 150 yards (meters) by the winds.
A man and woman with the bouncy castle company have been released on bail after being arrested on suspicion of manslaughter.
