A light plane is missing on a flight from St. Louis County to Texas. Searchers will go back into the air today after finding nothing in the Rolla area yesterday. Pilot Clarence Pruett did not file a flight plan. FAA radar records show a plane disappeared from the screens somewhere northwest of Rolla. Civil Air Patrol Lieutenant Randy Fuller says the only clue to go on is the report of a low-flying aircraft. Also making the search difficult is that the plane may be partially or entirely brown or beige, making it difficult to spot from the air.
