Near San Ignacio, Mexico is an area known as the Mexico Bermuda Triangle or Silent Zone. Both the Bermuda Triangle and the Silent Zone have similar legends. Reportedly radio waves cannot be transmitted in some areas of the zone, due to “earth energy” and magnetic fields. On 11 July 1970, the US Air Force lost an Athena rocket in a training exercise which ended up here. The rocket had two containers of Cobalt 57 on board, and it took weeks to find the rocket, leading to myths among the locals.
