&quot;Earths magnetic field...is on average it is about 30 Tesla, and 16 Tesla&#x27;s is about the force required to levitate a frog...So unless flying saucers weight just about as 2 mid sized frogs I&#x27;ll take the bet that if they do exist they use something else to keep them from crashing&quot;<p>Something about this doesn&#x27;t make sense. Probably has to do with the answer to this question: Why don&#x27;t frogs normally float due to the Earth&#x27;s magnetic field?
