ZitatA KLM Boeing 737-800, registration PH-BXE performing flight KL-1121 from Amsterdam (Netherlands) to Stockholm (Sweden) with 166 people on board, was enroute at FL370 about 40nm south of Billund (Denmark) when the crew reported problems with a pressure gauge and decided to return to Amsterdam. The aircraft landed safely back on Amsterdam's runway 18R about 50 minutes later.
Another KLM Boeing 737-800 had returned to Amsterdam a few hours earlier because of problems with the instruments, too, see Incident: KLM B738 near Amsterdam on Jan 10th 2014, instrument problems.
