<SNIPPAGE> <quote> The Wrong Sort of Planet They wouldn't listen to me; I did tell them; one good volcanic eruption and they're useless; they'll rue the day they decided on these newfangled jets and abandoned propellers! </quote> Non-UK readers need to know that the excuse used by the UK rail infrastructure company for difficulties keeping trains on time one recent autumn - appropriately also known as "fall" - was headlined as "The wrong sort of leaves". This last winter a similar excuse for transport disruption borrowed the headline as "The wrong sort of snow". And in case, you haven't seen the news, the air space of a large part of Western Europe has been closed since it turns out that the particles being put out by the volcano - situated so conveniently in the middle of the busiest air corridor on the planet, given their genesis, are particularly harmful to jet engines. Having sent the letter, I was amused to see that an aeroplane providing pictures of the eruption was - you guessed it - propeller-driven! <SNIPPAGE> At 160 KIAS (Knots Indicated Air Speed) and beyond (which Propeller aircraft are capable of), the ash and grit from a volcano is rather corrosive to the leading edges of wings, windshields, etc. But it is much more sensational for the unknowing reporters to say that jet engines are more susceptible to damage... However, having wings develop holey (not Holy) leading edges in flight tends to make flight crews into test pilots with no real warning... I would also imagine that the aircraft taking the pictures was making sure that they were staying clear of the ash plume.
