Yes I had thought of all the 9 letter ways of transport I could think of, and parachute was on the list but I can't quite reason why it is correct. Funicular was also on the list, perhaps some reference to perpendicular i.e. right angle clue?
If nobody else comes up with a better answer or explanation, I will go,with your answer. Thanks for your help Thewinner
you are welcome, but I have no idea if it is correct. Seeing as we haven't had much interaction on AB, please know that my user name is because I won £10 when I entered the local newspapers crossword. They published the results, with : and The Winner is: (+my name). I am not a winner because I am clever, quite the reverse.
