Not used to getting to getting agreement!
Trying to be careful with this because the precise facts are unclear. If the a/c was already back tracking before the landing a/c had turned finals I would have expected the landing a/c to extend the downwind or base leg or go round. If the landed a/c simply turned and bac tracked without looking for possible conflicting (not just listening for a call) then he could have been in the wrong.
Don't really want to be drawn on the particular case because individual perspectives might differ in important respects from the facts (a natural typical human response), and I don't want to suggest that SS could have acted differently - I don't know.
I do know that if SS had continued ahead to the 'C' hold and pulled off before seeking to back track (rather than landing short and immediately back tracking) he would probably have seen the approaching a/c and avoided any possible conflict (this common sense approach does not require published procedures).
He would have been inconvenienced a little. The other guy might have felt that he had somehow 'won' but the level of induced 'air rage' might have been reduced a little.
For the avoidance of doubt I am not suggesting that SS was in any way wrong in his actions nor that he should follow the procedure I suggest in my post in the future to avoid possible conflict. Others, however, when visiting an airfield such as this for the first time might benefit from taxying to a safe place (ie the 'C' hold in this case - which is identified in Pooleys and the CAA publications and a part of a 'disused' runway but still a 'used' taxiway / hold) before re-entering to back track.
