| 摘要： | In an age where "real men" walked around on steel beams hundreds of feet in the air building skyscrapers, the Golden Gate Bridge product raised eyebrows by stringing a large safety net under the slowly expanding span. But even with the net in place, dropped tools and building materials (usually rivets) were commonplace. And if a blow to the head knocked a worker unconscious, a fall was certain. Tumbling to certain death in the cold waters of San Francisco Bay far below was a possibility, since there was no guarantee he'd actually land in the safety net. |
