Last year, a 10-year contract between Boeing Commercial Airplane Group (BCAG) and Thyssen Inc. - a distributor of raw aluminum - expired.

Declines in the demand for commercial aircraft during the past decade led some analysts to challenge BCA's wisdom in signing such a long-term contract. Do you share this view? Explain.`
