Although the Boeing design had been the first to enter series production, the 247 proved to have some serious design deficiencies.

Most of the severe effects of that event were due to poorly responding soil conditions and design deficiencies in large structures.

Carl Sagan, among others, has pointed out important design deficiencies for such a goal in the large manned station.

While there are no reports of successful escapes via this route, it was raised by Inspectors as an obvious design deficiency.

"We felt that even if we got away with it, the serious design deficiencies might later be disastrous," says David Walker.

The commission said it had found design deficiencies similar to the ones found at Millstone 1 and 2.

Like others of her type, she was modified during the middle 1930s, both to correct design deficiencies and to enhance combat capabilities.

Government reports subsequently blamed design deficiencies and maintenance procedures for the crash.

"AMR's efforts to reduce costs may help the margin, but they don't address the basic design deficiency of its business plan."

Per-unit costs in mid-2006 were 25% over baseline estimates, caused by both the need to correct design deficiencies as well as increase the system's capabilities.
