Turns out that the most likely explanation for all those disappearances is rough weather in the area. Many of the survivors who had some trouble in the Bermuda Triangle have reported cyclones and such things. | |

| Apr 11, 2018 at 21:48 | comment | added | Graipher | @Muze There is no "focused magnetic beam". The closest to that is electro-magnetic radiation, also known as "light". So yes, you could theoretically have a laser strong enough to move a plane (which would have a strong magnetic field as part of how it propagates), but that laser will probably have enough power to also pulverize the plane and ionize the atmosphere in front of and behind it. (If I did not make a mistake somewhere in my calculations, it is somewhere between the entire energy of the sun hitting the Earth in one day and the impact of the meteor that killed the dinosaurs). | |

| Apr 11, 2018 at 20:20 | comment | added | Graipher | @Muze No. Even if it was strong enough to move a plane when a meter away, the electro-magnetic force diminishes with one over the distance squared. At 10km up it would be a hundred million times less strong. | |
| Apr 11, 2018 at 20:12 | comment | added | Muze | Would it be strong enough to pull a plane out of the air? | |
| Apr 11, 2018 at 11:17 | comment | added | Graipher | @Overmind 1. See my last paragraph. 2. That is stretching the definition of "on Earth" even more, but an answer with that would also be interesting. | |
