It was an eerie sight for a motorist driving Interstate 526 in South Carolina - a helicopter in the distance spewing smoke as it plunged toward the Wando River.

The Post and Courier of Charleston reports the motorist called 911 with the report Wednesday. Police and three Charleston Fire Department trucks and a fire battalion chief raced to the scene.

One Charleston police officer drove calmly by after seeing the truth. It was a helicopter all right - a remote controlled toy helicopter about 2 feet long.

Police spokesman Charles Francis says two people were below the interstate bridge operating the toy chopper when it went down.
