Driver of jet-propelled truck killed in high-speed crash at air show in Michigan

The driver of a truck powered by jet engines was killed during a high-speed accident in front of spectators at an air show in Michigan, police and relatives said Sunday.

Chris Darnell, 40, died Saturday at the Battle Creek Field of Flight Air Show, where he was driving the SHOCKWAVE Jet Truck down a runway at more than 300 miles per hour, police said in a statement.

"We have lost our youngest son Chris in an accident doing what he loved; performing with SHOCKWAVE," his father Neal Darnell said on Facebook. In a separate post, he said the accident was a result of "a mechanical failure on the Jet Truck."
