Purely hypothetical question on aviation law.

In maritime salvage if your craft rescues/tows/supplies crew to a stricken vessel then you can claim a reward based on the value of the craft and cargo.

Let's assume that you are flying off somewhere warm for a few weeks in a commercial airliner and hear the call "Is there a pilot on board"... and let's all be honest every pilot has fantasised about it.

If you manage to take control of the aircraft and land it safely, does salvage law apply similar to maritime salvage laws? I cannot find anything online that covers it but it must have happened at some point in history.
