A pilot died in the Quad-City Air Show on Saturday when the jet he was flying crashed into a field in northern Davenport.

Glenn Smith, 59, of Frisco, Texas, was flying in formation along with other members of Hopper Demo Flight Team around 1:30 p.m. at the annual Quad-City Air Show in Davenport Iowa. His L-39 jet crashed into a field alongside the I-80 highway near the Eastern Iowa Industrial Center.

The L-39 jet was a Soviet-era military training jet developed in the former Czechoslovakia in the late 1960s.

There were no injuries or reports of any damage on the ground.

Smith was a pilot and a long-time entrepreneur for Tyler Technologies, a Dallas based company that develops software for local schools and government.

After retirement, Smith continued to fly. His jets are displayed at the Historic Aviation Memorial Museum in Tyler, at the Tyler Pounds Regional Airport.

The National Transportation Safety Board is investigating the crash.
