The Dallas woman who was killed Thursday when a float plane crashed in Lewisville Lake has been identified as 41-year-old Kristin Kolby.

Police in The Colony didn't release the name of the pilot, a man who was pulled from the wreckage by two brothers and taken by air ambulance to Parkland Memorial Hospital.

The plane is registered to Kenneth Gedney. Gedney, 54, was listed in good condition today at Parkland Memorial Hospital, a hospital spokesman said.

Johnny and Nathan Hopkins saw the airplane hovering over the lake about 4 p.m. and watched it descend on to the placid water near Stewart Peninsula Park in The Colony.

"He flew by and belly-flopped," Johnny Hopkins said.

He said the plane landed on its pontoons and flipped upside-down, submerging its cabin.

"It went down in about 20 seconds," he said.

The brothers saw an unconscious man bobbing in the water, and Johnny Hopkins jumped in and pulled him to his boat. He said he administered CPR for two minutes before the man regained consciousness, spitting up lake water.

The man was taken by air ambulance to Parkland. Kolby died at the scene, according to the Tarrant County medical examiner's office.

Emergency personnel from The Colony and Lewisville retrieved the wreckage of the plane, The Colony fire chief said.

For several hours after the crash, the plane’s cabin was submerged with only its floats sticking out of the water. The airplane’s landing wheels, which normally are stowed during water landings, extended from the wheel wells.

The National Transportation Safety Board will investigate the accident.
