This unfortunate Essendon accident is little different to that which occurred on October 30, 2014 at Wichita Mid-Continent Airport, also involving a King Air 200. The aircraft impacted the FlightSafety International simulator complex. The pilot was fatally injured, three building occupants were fatally injured (ironically in a simulator undergoing training), two occupants sustained serious injuries, and four occupants sustained minor injuries. At the time about one hundred people occupied the building.
