SANDTOWN, Del. (AP) — A Pennsylvania man was critically injured when the crop duster plane he was flying crashed into a Delaware field.

Delaware state police Master Cpl. Gary Fourier tells local media that the man injured on Wednesday was 52-year-old Carlisle resident Robert E. Waring.

A preliminary investigation has found that Waring was operating a 1964 Grumman G-164 fixed-wing single-engine crop duster over a cornfield southwest of Sandtown. After spraying the corn, Waring began to pull the plane up and clipped some electrical wires on the west side of a road.

Fourier says Waring then lost control of the plane and crashed into a nearby bean field.

Waring was airlifted to Bayhealth Kent General Hospital where he was listed in critical condition.

Authorities are continuing to investigate the crash.
