Authorities in Indiana, USA, have said two firefighters were killed on Sunday after their plane crashed into another at Marion Municipal Airport.
The firefighters, Kyle Hibst and David Wittkamper were the only people aboard the single-engine plane when it struck the tail of a larger plane, which had just landed at the airport, authorities said.
The parked plane had five aboard, according to the Federal Aviation Administration. Their conditions were not immediately clear.
Hibst and Wittkamper were firefighters at the Pipe Creek Fire Department in central Indiana.
“It is with great sadness and sorrow we announce the passing of two of our own. Words cannot express the pain and loss each of us feel. Our hearts go out to both families involved. Rest easy brothers. We will take it from here," the department wrote on its Facebook page.
Hibst, who had been with the fire department for about seven years, was married with one son, according to the statement. His wife, Kim, was also a member of the fire department.
Wittkamper joined the department in 2007, the statement said. He is survived by his wife, Autumn.
The FAA and the National Transportation Safety Board are investigating the incident.
