Apologies, slightly off topic;
@Arfur Dent "That's why in the old days on little aircraft we always aimed to land a third of the way up the runway on a PFL."
This is a very interesting point. As a PPL student I take on board all of the sound advice I can get. A veteran pilot told me recently to learn to think "what could go wrong here?" and (prepare to) act accordingly. An example he gave me was when approaching a runway with plenty of room consider landing one third down the length of the runway, an engine failure at the last moment suddenly won't be so bad.
