NEW MADRID, Mo. -- The Missouri Department of Natural Resources is overseeing cleanup of fuel and fertilizer after a crop duster airplane crashed upon takeoff in Southeast Missouri.

The pilot was not injured in the crash that happened Monday afternoon in New Madrid County. The plane is owned by Ag Air of Matthews, Mo.

DNR officials said Tuesday that the plane came to rest in a waterway and began leaking fuel and fertilizer. The DNR is trying to determine the extent of environmental damage, though it is known that the spill caused some fish to die.

The Federal Aviation Administration is investigating the cause of the crash.
