I recall that Nigel in one of his 777's taxied to and took off unintentionally from a very short intersection in St Kitts. Strangely enough, yet again an 'engineer' passenger advised the cabin crew during taxi that the aircraft was taxiing to the wrong runway entry point. Subsequently, a big song and dance was made as to how important it is to heed information eminating from the cabin as a reult of that cock up. It seems that this advice has not penetrated the ethos of Ryanair operations.
