[2] Ozark Air Lines Flight 650 was operated using a McDonnell Douglas DC-9-31 twin-engine, single-aisle jet airliner (registration N994Z).

[1]: 17 Flight 650 departed Sioux City at 12:53 Central Standard Time, and climbed to an assigned altitude of 11,000 feet.

The impact ripped the right wing from the plane, destroying the snow plow and killing its driver, Douglas Stoner, age 38.

[3] Leaking fuel from the wing briefly created a fireball that engulfed the airplane but rapidly died out.

The snow plow, call sign Sweeper 7, had been routinely directed to exit the runway to accommodate arrivals and departures.

[1] The aircraft involved in the accident was eventually returned to service with a replacement right wing salvaged from Air Canada Flight 797 that had its main fuselage destroyed by fire after an emergency landing at Cincinnati/Northern Kentucky International Airport earlier that year.
