A married couple from Iowa was killed Friday afternoon when their plane crashed in Hopkinsville, Kentucky. Christian County emergency officials identified them as 69-year-old Dominic and Dr. Dianne Giammetta, 55, of Bettendorf, Iowa. Officials with the National Transportation Safety Board arrived on the scene Saturday morning to begin a two to three day process of speaking with witnesses, analyzing the wreckage, and working to determine the cause of the crash. According to an NTSB spokesperson, the plane was en route from Davenport, Iowa, to Muscle Shoals, Alabama, when it went down. A representative at Northwest Regional Airport in Muscle Shoals learned the plane was supposed to land between 2 p.m. and 3 p.m. Friday. The area is a popular stopping place for people traveling from the Midwest to Florida. The Federal Aviation Administration identified the aircraft as a Beechcraft Bonanza BE36, a small single-engine aircraft with six seats. The FAA is investigating alongside the NTSB. The governor of Kentucky, Matt Bevin, released a statement Friday night that says, “We’ve received word of a multiple fatality plane crash in Hopkinsville. For all Kentuckians who understand the power of prayer, please join me in praying for the families and friends of those affected, and for strength and wisdom for our first responders.”
