Well done- I was joking of course, I am amazed that you even thought for a moment that I could be serious. I thought a little light heartedness on this forum, where everyone takes themselves so seriously, would not go amiss. I think at least Captain Airclues appreciated my "stupid" answer and thought it might make the basis of a cartoon by figment.
I am sorry it did not amuse you.
