15329 Sabena           Discovered 1993 Sept. 17 by E. W. Elst at the European Southern Observatory.
Sabena was the National Belgian airline but had to stop its activities due to financial problems. This minor planet is dedicated to the flight crews and ground personnel, who did a marvelous job during all the years Sabena was flying.
