Following the 9/11 terrorist attacks and the outbreak of rescue operations after physical conflicts, multiple police officers and firefighters died during the rescue. Welles Remy Crowther, a Wall Street trader and volunteer firefighter, tragically lost his life while saving people, and his red bandana became an iconic item. The fires at the ruins of the New York World Trade Center burned continuously for three months, and rescue and cleanup operations lasted for nine months. Hundreds of public servants from the New York City Police Department, the Port Authority Police Department, the Court, and the Fire Department sacrificed their lives.

### 起因
2001年9月11日上午8时46分及9时03分，基地组织恐怖分子劫持的美国航空11号班机和联合航空175号班机先后高速撞击纽约世贸中心北塔与南塔，引发大面积航空煤油剧烈爆燃并迅速破坏核心钢结构支撑。

### 经过
纽约消防局与警方接到警报后即刻启动最高级别应急响应，大批指战员梯队冲入双子塔高层楼梯通道开展疏散救援。由于现场内部高频无线电中继通讯系统发生严重技术故障，当南塔与北塔分别于9时59分和10时28分发生灾难性粉碎坍塌时，身处塔内深处的众多救援人员未能接收到撤离指令，伴随巨量钢筋混凝土废墟一同被埋遇难。平民英雄如韦尔斯·克劳瑟凭借红头巾辨识度在火海中反复引导疏散直至生命最后一刻。

### 各方说法
9/11事件独立调查委员会在后续调查报告中高度盛赞公职人员舍生取义的英雄主义精神，同时指出了跨部门指挥协调不力、通讯设备互通性差等体制性短板；全美社会与国际舆论对殉职警消致以崇高敬意。

### 处理结果与后续
救援与遗骸清理行动持续开展至2002年5月30日始告正式结束。双塔遗址随后被建设为“归零地”九一一国家纪念博物馆，所有殉职公职人员名字被铭刻在青铜水池边缘供世人永久铭记瞻仰。
