KLM flight #KL777 to Saint Martin is returning to Amsterdam following a technical issue.
The flight is operated by an Airbus A330-200 (reg. PH-AOE) which is 17 years old.
The aircraft took off from Amsterdam at 11:15 CET but while flying over Dublin, the crew decided to divert.
It just turned around at 31,000ft before heading to South and dumped fuel over the sea.
The A330 was then seen over London, returning to Amsterdam.
The airline is informing AIRLIVE that the flight is cancelled.
