当局称，周日，两架直升机在费城郊区的一个镇上空相撞并坠毁，造成至少一人死亡，另一人重伤。
据美国美国联邦航空管理局(FAA)称，坠机事件发生在下午12点25分左右，地点在新泽西州的哈蒙顿，距离费城东南约35英里。
美国联邦航空局表示，一架Enstrom F-28A直升机和一架Enstrom 280C直升机在汉蒙顿市政机场附近“在半空中相撞”。
据警方称，相撞后，两架直升机都垂直坠落到地面，降落在盆地路100街区附近。据汉蒙顿警察局称，其中一架直升机“被火焰吞没”。
据警方称，“现已确认有一人死亡，一名受重伤者由急救医疗队运送。”。
当局称，警察和EMS工作人员扑灭了火焰。
美国联邦航空局表示，美国国家运输安全委员会接到了坠机通知，正在派出一个小组进行调查。
目击者布莱恩·谢尔说，当他听到附近的一名妇女“尖叫着，‘哦，我的上帝，哦，我的上帝’”时，他正在附近的一家商店外面。"
“我确实听到了金属碰撞声，但周围有很多车辆，所以我没有太注意，”Sherr告诉ABC新闻。
他说，当他仰望天空时，他看到其中一架直升机“以旋转的方式慢慢下降，几乎就像方向舵和尾翼失去了控制一样。”
“起初我以为这是唯一的一架，然后我看到第二架直升机落下来，后面也有同样的问题，”谢尔说，并补充说，他看到第二架直升机撞击地面后浓烟升起，促使他拨打了911。
遇难者和受伤者的姓名没有立即公布。
汉蒙顿警察局表示，调查人员要求居民和旅行者在接到进一步通知前避开盆地路地区。
2 helicopters collide in New Jersey; 1 person dead, another critically injured, say officials
At least one person was killed and another critically injured on Sunday when two helicopters collided midair and crashed in a suburban Philadelphia town, authorities said.
The crash occurred around 12:25 p.m. in Hammonton, New Jersey, about 35 miles southeast of Philadelphia, according to the Federal Aviation Administration (FAA).
The FAA said an Enstrom F-28A helicopter and an Enstrom 280C helicopter "collided in midair" near the Hammonton Municipal Airport.
After colliding, both helicopters plummeted to the ground, landing near the 100 block of Basin Road, according to police. One of the helicopters became "engulfed in flames," according to the Hammonton Police Department.
"There is confirmed one fatality at this point and one subject transported by EMS with critical life-threatening injuries," according to police.
Police officers and EMS workers extinguished the flames, authorities said.
The FAA said that the National Transportation Safety Board was notified of the crash and is sending a team to investigate.
Witness Brian Sherr said he was outside of a nearby store when he heard a woman nearby "screaming, 'Oh my God, oh my God.'"
"I did hear a metal clank, but there's a lot of vehicles around, so I didn't really pay much attention," Sherr told ABC News.
He said that as he looked up to the sky, he saw one of the helicopters "slowly descending in a rotating motion, almost as if the rudder and the tail had lost control."
"I thought that was the only one at first, and then I see a second one come down with the same issue behind it," Sherr said, adding he saw smoke rise after the second helicopter impacted the ground, prompting him to call 911.
The names of the person killed and the person injured were not immediately released.
The Hammonton Police Department said investigators asked that residents and travelers avoid the Basin Road area until further notice.
