With all due respect, what do you mean for a lovely concrete block? I just would like to understand it correctly.
This is more British humour! By using the word 'lovely' that would not normally be used in this context the writer, Fargoo, was highlighting the misfortune of the pilot. Had the wheels met a large signpost instead or a big patch of mud, then the same 'lovely' might have been used. It is one of those uses of colloquial English in the South East of England that is almost impossible to explain!!
