That certainly is my reaction to this thread.
I remember that I fairly recently raised the issue on part of these boards of what if any EU rules exist to oblige airlines to roster cabin crews who are able to express themselves in the languages of the arrival and destinations towns of the flight.
The answer was "none."
Apart from issues of lack of commission from trolleys, of 50p per week as a bonus or of dinky little flags, not to mention the aimiabilty of cabin crew on this named airline or on that, the concept of an emergency in these anarchic conditions does not bear thinking about.
Presumably, as always, this will be rectified in the future; after some (many many ?) poor blighters have died or been maimed for this basic reason.
And to think that today in the UK the Prime Minister gave a speech about responsible and compassionate capitalism. Not much sign of that in the under-regulated dog eat dog airline business we currently have.
Most aircraft have language PA's along side English that can be played in an emergency. Commands use strong positive body language along side words (usually not enough time when shouting commands to do it in two languages) and in preparation for an emergency landing we would most certainly get the message across......it really wouldn't be too difficult. The picture you paint is, quite frankly, rubbish and from past incidents there is nothing to support your claim.
