摘要

As Boeing Struggles To Get The Latest version of the 747 to first flight, there is more than a touch of deja vu to the situation, recalling as it does events in Seattle 40 years ago this past February when the first 747 took to the air. Across a span of four decades, the company confronts similar issues on the 747-8, as strained engineering resources and delays dog the program again. In the late 1960s, Boeing's resources were stretched to the absolute limit as its engineers grappled with the complexities of its 2707 supersonic transport, which eventually was scrapped by Congress on May 20, 1971, despite commitments for 115 from 25 airlines. At the time, the 747 was considered only an interim solution, an aircraft for economy class while well-heeled travelers went supersonic. The manufacturer had assigned most of its top engineering talent to the SST project.
