GBS, roger, understood and good point!
I realise that the firemen are at Oban as a result of licensing requirements, but I'm very happy that someone is there to extract me if I cock it up in my wee spamcan. I do on occasion also operate to places where it is entirely up to me to extract myself (and more importantly any pax), which wouldn't have potentially as happy a result. Is it worth a proportion of a reasonable landing fee? To me, yes.
