Two KLM aircraft were forced to return to Schiphol airport on Sunday night because of technical problems.

The first, a Boeing 777-200, was heading for Shanghai but returned to the Netherlands after three hours of flying time. The airline told news agency ANP there were problems with the drinking water supplies. It landed at Schiphol around 11.30 pm.

The second, a Boeing 777-300 was heading for Bali but turned back shortly after taking off. KLM blamed a technical problem but did not give further details.

That incident was the third involving a KLM Boeing in two days. On Saturday evening a flight had to make an emergency landing in the far south of Norway.

The Boeing 737 was heading from Oslo to Amsterdam when the pilots heard a “loud noise” 20 minutes after take off. They decided to head for Torp Sandefjord airport rather than continue their journey.
