[2] The most powerful tornado was located around Manchester in Kingsbury County and was rated an F4 on the Fujita scale.
In the National Weather Service survey released shortly after the tornado, winds were estimated to be up to 260 miles per hour.
Manchester was never rebuilt and is now a "ghost town" with some farm buildings but otherwise no houses or stores.
The twister passed right over one of the sensors which recorded a 100 millibar pressure drop.
One film shot showed the tornado passing directly over a camera placed and buried on the ground.
