In September last year, a fraud squad, led by Jean-Claude Van Espen, a Belgian magistrate, raided Airbus's headquarters in Toulouse. "They wanted to check whether there was possible falsification of documents, bribery or other infractions as part of the sale of Airbus aircraft to Sabena," says Mr. Van Espen's spokes- man. The team of 20 Belgian and French investigators interviewed several Airbus employees during its three-day stay in Toulouse and carted away boxes of documents.
