A small plane crashed Sunday afternoon onto an expressway in suburban Chicago while trying to make an emergency landing, authorities said. No serious injuries were reported.

The plane didn't hit any vehicles on the highway, said Illinois State Police Master Sgt. Ted Vernon.

The plane, carrying flight instructor John R. Vafhko, 63, and student Kenneth Mattuck Jr., 18, crashed around 12:40 p.m. on the Elgin-O'Hare Expressway, less than a mile from the Schaumburg Regional Airport, Vernon said.

Vafhko was hospitalized with a head wound and was listed in fair condition, hospital officials said.

The student walked away uninjured, Vernon said.

The plane had just taken off from the airport when it experienced engine trouble. The instructor first tried to turn the plane around, but the engines went out and he tried to glide it down onto the highway, Vernon said.

The Federal Aviation Administration did not immediately return a call seeking comment, but a recorded message said the agency was investigating the accident.
