But the benefits of the government purchase extended beyond its specific goal, when Boeing used the knowhow it acquired developing the B-52 to create its commercial B-707 aircraft. Though the government never purposely promoted the development of commercial airplanes, its procurement of high-quality, technologically advanced military aircraft was essential to the emergence of America’s globally dominant commercial aircraft industry.
但政府采购的好处不局限于具体的目标，后来波音使用其从研发B-52中获得的知识建造了B-707商用飞机。尽管政府从未有意识地促进商用飞机的开发，但其采购高质量、高科技军用飞机的行为对于美国获得全球商用飞机行业主宰地位功不可没。
