The Chicago pilot who died in a small plane crash at Schaumburg Regional Airport has been identified by investigators.
The aircraft went airborne before nose-diving into a grassy area near the airport's runway, the Chicago Tribune reports.
Witnesses on the ground said the plane soared about a 100-feet but then "fell out of the sky."
When we drove over to the scene to help him, "it was obvious he was dead," said Paprocki.
Federal Aviation Administration records show Borgstrom was licensed as a flight instructor and commercial pilot for single-engine planes, The Daily Herald reports.
The FAA and Illinois State police are trying to piece together what caused the crash.
