Thank you for the concise description of the events, posts #18, 21 & 33 had already raised this as being the most likely chain of events but it is always helpfull to get the precise detail.
However the posts from some above seem to prove that some are incapable of reading and understanding a safety card, let alone the technical issues described by the wiser contributors to this thread.
A job well done by the flight crew, cabin crew and fire service in my opinion.
