At some point if you can’t trust the captain of your vessel, that person can disrupt or disable most any system put in place.&lt;p&gt;If the captain of the titanic intended on sinking the ship without a trace, he most certainly would have succeeded as well.&lt;p&gt;A more apt comparison would be AF447, which took a few days before the wreckage was found. &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.m.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Air_France_Flight_447&quot; rel=&quot;nofollow noreferrer&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.m.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Air_France_Flight_447&lt;/a&gt;</text><parent_chain><item><author>ajsnigrutin</author><text>Is there some good explanation, show a sinking titanic was heard both in london and new york, but a modern(...ish) MH-370 can just dissapear?&lt;p&gt;I&amp;#x27;m sure that there are a bunch of factors in play, but tracking a plane seems like a relatively simple and a high priority thing to do, and relatively cheap compared to a total cost of a plane.

The Titanic was actively sending out distress signals via telegraph as it sank, but those signals weren&amp;#x27;t strong enough to reach land. They were picked up by other nearby vessels and relayed.</text><parent_chain><item><author>ajsnigrutin</author><text>Is there some good explanation, show a sinking titanic was heard both in london and new york, but a modern(...ish) MH-370 can just dissapear?&lt;p&gt;I&amp;#x27;m sure that there are a bunch of factors in play, but tracking a plane seems like a relatively simple and a high priority thing to do, and relatively cheap compared to a total cost of a plane.
