As absolutely incredible as it may sound bob, some people infact DO own aircraft!
...the hypothetical situation may have some relevancy to someone who purchases their own aircraft to train in stages and wants to fly for a while between the issue of an RPL and later nav endorsement or full PPL.
7700... It's would appear it's not that simple. I have seen no mention of a landing away prohibition, and that means at some point the origin of the flight could change from the point where the aircraft is originally based. The situation could arise that the aircraft moves to a different home base 24.5 miles from previously. Are you suggesting then that it could only fly in one direction?
