Last night Ryanair flight 7312 from Dublin to Zadar, Croatia diverted to Frankfurt Hahn airport in Germany after it lost cabin pressure.
The Boeing 737-800 had 189 people on board and was flying at 37,000 feet 120 miles southwest of Hahn airport at the time of the incident. Passengers reported hearing a bang. The flight crew deployed passenger oxygen masks and made an emergency descent all the way down to 8000 feet.
