I'd like to think that the airships in MH have some sort of space-bending tech that allows it to switch dimesions and/or timelines in order for the hunter to hunt the same monster as many times as they like. This would also explain why the monsters appear in the same area in a quest every time you visit that quest. It is literally the same monster! But that's just my interpretation of it :P
