I wish I had the money to conduct an experiment. In a warehouse I'd have about a 20ft sea vessel. I'd have it rigged up were it would move and feel like you were on the sea. I'd have it look like a moving ocean with holographic movie images. At least 10 men and women of different backgrounds and ages. I'd manipulate the magnetic fields to mess up the compass. Rock the some. I'd want to see after 24 hours, if the people start to lose it mentally. No? Then 36 hours, 72 hours. The boat would be fully stocked with food and water. I would want to see if the magnetic field messes up their mind to a point that they want to drown themselves. Or do harm to themselves or others. If that's the case it could explain why no people found from boats. Planes, on the other hand, we really have no way of knowing. If they crashed into the sea, their would be no bodies because of sharks and drowning.
