CHICAGO (AP) _ A small plane went off the runway into Lake Michigan near Meigs Field on Thursday, the Coast Guard said.

The plane went into the water at about 8:30 p.m., a Coast Guard petty officer said. Rescue crews were en route via boat, and other emergency vehicles were on the scene.

It was not immediately known how many people were on board the plane, or if any people were in the water.

Meigs Field is a small airport with a single runway on Chicago's lakefront near the Loop. It sits near the Adler Planetarium, Field Museum and Shedd Aquarium.
