* Lockheed Martin Corp. has received permission from the Justice Department to sell its flight controls unit for $510 million to Britain’s BAE Systems, Europe’s largest defense contractor. The Lockheed unit, which is based in Johnson City, N.Y., and Fort Wayne, Ind., makes engine and fly-by-wire controls and other aircraft parts. Lockheed Martin is shedding assets and reorganizing after profit warnings last year cut its share price by almost half. Lockheed shares fell 19 cents to close at $28.25 on the NYSE.
