Ryanair, the biggest no-frills airline in Europe, has been criticized by the Irish Air Accident Investigation Unit for an incident that occured in September, last year. Nine oxigen masks failed to deploy and the cabin crew had to bang on the cockpit to make them come out.

Because of panick and bad trained received from the company, the crew had to use ID cards in a desperate attempt to force the oxigen masks to come out, according to a report made public by the Air Accident Investigation Unit. The report criticizes the crew for continuing pressurising the cabin despite the fact that the nature of the incident was not known.

A sudden loss in pressure occured when the flight crew checked the tail that hit the runway before taking off. The flight heading from Dublin to London Stansted on September 11th 2008 was carrying 6 crew members and 148 passengers. More about the incident can be found here.

It’s not the first time Ryanair’s negligence hits the spotlight. We addresssed a similar issue before, when Ryanair fuel saving practices interfered with European regulations.
