So if it is identified in less than 500 minutes then who has control - the original poster again?
No, I've assumed its exactly how we play today, save that if it passes the 500 mins then the poster claims the Noyade 500 prize (whatever that may be) and has the right to post again.
If it goes before the time is up then whoever gets it wins and posts their challenge.
In fairness nothing changes save that the poster can claim the prize if their image survives 500 mins and they can demonstrate that more than 500 aircraft were produced.
Anyway I was just thinking about it as I have a quiet afternoon!
