A plane traveling from Houston to Tulsa, Oklahoma crashed in Wells, Texas Monday night and left its pilot and sole occupant killed.

Cherokee County officials said they had received calls just before 10 p.m. from witnesses who reported seeing something “fall from the sky, heard a boom, and saw a fire.”

According to Department of Public Safety, a single-engine Cessna 421 was flying during a thunderstorm at 24,000 feet over Cherokee County at 9:22 p.m. when the pilot lost control of the plane and hit the ground.

The plane exploded upon impact.

The pilot was identified as 64-year-old John Thomas Steeper of Broken Bow, Oklahoma.

FAA spokesman Lynn Lunsford said air traffic controllers lost contact with the plane as Steeper, an engineer who often traveled to Texas on business, tried to navigate through the storm.

The public flight-tracking website Flight Aware shows the aircraft originated in Houston at 8:41 p.m., and was due to arrive in Tulsa about 2 hours later.
