1975: An Eastern Airlines Boeing 727 crashed at JFK airport in New York City. 113 of the 124 people on board the aircraft died. Researcher Theodore Fujita studied the incident and discovered that a microburst caused the crash. His research led to improved air safety. The tower never experienced the microburst, which was held back by a sea-breeze front. The plane crashed 2,400 feet short of the runway.
2003: An F4 tornado destroyed or heavily damaged all buildings, other structures, and vehicles in the small town of Manchester, in Kingsbury County. Many homes were stripped to the foundation. Of the six residents of the town, four were injured and were transported to hospitals. Three were deemed to be severely injured, but none of the injuries were listed as life-threatening. Throughout the path, the tornado was observed to have multiple vortices. The tornado was seen and videotaped by many storm chasers and researchers. Researchers also deployed weather sensors around the town of Manchester. One of these sensors recorded a 100 millibar pressure drop as the tornado passed. This tornado was part of a larger outbreak in eastern South Dakota, which experienced a record 67 tornadoes within an eight-hour time frame.
