Who owns wrecked airplanes in international waters and in terra nullis?
<p>This question has been suggested to be transferred from <a href="https://aviation.stackexchange.com/questions/26377/who-owns-wrecked-airplanes-in-international-waters">Aviation site</a>. However I have expanded my question also applicable to terra nullis (like <a href="https://en.wikipedia.org/wiki/Bir_Tawil" rel="nofollow noreferrer">Bir Tawil</a>)</p>

<p>So, assuming we have a wrecked airplane located in international waters or in terra nullis (is any of both terms making a difference?):</p>

<ul>
<li>Who can own the remains of the ship and cargo? Can anybody claim them if found?</li>
<li>Is there any difference between floating debris (for international waters) and sunk debris?</li>
</ul>

<p>In my original question it has been answered that <a href="http://www.emsa.europa.eu/retro/Docs/marine_casualties/annex_13.pdf" rel="nofollow noreferrer">ICAO Annex 13</a> covers the case of civil airplanes, countries belonging to ICAO and accident investigation (so not fully covered). My understanding is that the "State of Registry" or the "State of the Operator" will make the decision of who owns the remainings afterwards.</p>

<p>The person who owned them before they were wrecked. If you crash your car, does that mean you no longer own it?</p>

<p>There are detailed international laws governing the rights of <em>salvage</em> of wrecks and there will almost certainly be insurance contracts involved that may change the owner but unless and until these kick in the owner is the owner.</p>

<p><strong>Not directly</strong>, but you can get some reward for salvaging it and there is the possibility that the reward is keeping it.  Wikipedia has a section on this in <a href="https://en.wikipedia.org/wiki/Marine_salvage" rel="nofollow noreferrer">their Admiralty Law coverage</a> as well as a <a href="https://en.wikipedia.org/wiki/Law_of_salvage" rel="nofollow noreferrer">separate article on the Law of salvage</a>.</p>
