Firefighters battle a blaze that gutted two homes in Sanford, Fla., after a twin-engine plane crashed and struck the houses, killing five people. Dr. Bruce Kennedy, a Daytona Beach plastic surgeon and husband of International Speedway Corporation President Lesa France Kennedy, was among the people killed in Tuesday's crash.

Sanford, Fla. ? A small plane carrying the husband of a NASCAR executive crashed into a neighborhood Tuesday and engulfed two houses in flames, killing both people aboard the aircraft and three others on the ground.

The pilot had reported smoke in the cockpit and was trying to make an emergency landing when the twin-engine plane went down in suburban Orlando, officials said.

NASCAR confirmed that 54-year-old Dr. Bruce Kennedy, a Daytona Beach plastic surgeon and husband of International Speedway Corp. President Lesa France Kennedy, and NASCAR Aviation pilot Michael Klemm, 56, were among the dead.

It was not entirely clear who was flying the plane. NASCAR said it was Kennedy, but investigators said earlier Tuesday it was Klemm.

Janise Joseph-Woodard, 24, and her 6-month-old son, Joseph Woodard, were killed when the home they were in was hit by the plane, police said. The young mother was a first-year law student at Florida A&M University College of Law, school officials and a former employer said.

Also killed was a 4-year-old girl, Gabriela Dechat, who was in a second home. Her parents, Milagros Dechat, 33, and Peter Dechat, 36, were seriously injured and transported to Orlando Regional Medical Center, police said.

A 10-year-old boy also in that home was transported to Cincinnati Burn Center with burns over 80 percent to 90 percent of his body, authorities said. The boy’s name has not been released.

Eric Domnitz, who lives just down the street from the crash site, hurried to the scene with a fire extinguisher and said he saw some of the victims.

“It’s in my head. The woman was just melting. It looked like her skin was just melting off,” he said. “The guy, he was melting. He looked like wax.”

Matt Minnetto, an investigator with the Sanford Fire Department, said the plane itself was scattered in several pieces.
