自上次报道以来的变化

6 天后

当时

载有9人的Learjet 60在Cresthaven附近坠毁；伤亡情况未确认

现在

机上9人全部遇难，附近数百名居民被迫离家。调查人员已经找回一段发动机，但在数英里外发现的尾部碎片使关键的因果顺序仍未明朗。

Stephanie Platts和家人在一架Learjet于佛罗里达州Greenacres附近坠毁时，逃离了蔓延至他们房产的火焰和燃烧碎片。她说，他们的家没能幸免。在11月5日的一篇报道中，Platts暂时住在Greenacres社区中心，并得到棕榈滩教区天主教慈善机构的帮助。她讲述了家人逃离时自己脚部被烧伤的经历。虽然他们在坠机现场幸存下来，却随即面临另一场紧急状况：寻找住处。⁠8

调查人员如今已抵达军事步道那片被毁区域下方掩埋的部分残骸。美国国家运输安全委员会（NTSB）11月5日的通报称，工作人员在挖掘过程中找回了一台发动机的一部分。在其他地方，距撞击坑数英里处发现的尾翼操纵面碎片表明，飞机在撞地前已经解体。这两项发现都尚未解释紧急状况是如何开始的。⁠224⁠10

我们在11月1日的节目中报道，一架载有9人的Learjet 60在Cresthaven附近坠毁，但当时无法确认机上人员的状况。如今已确认9人全部遇难：两名机组人员和七名乘客，其中包括两名年幼的孩子。交通部长Sean Duffy确认了这一死亡结果。⁠41⁠24⁠13

9机上遇难人数 24
1.3–3.8英里找回的升降舵碎片距坠机点的距离 10
400–600估计被迫离家的居民人数 255

这架喷气式飞机于2026年11月1日星期日中午1点前不久，在棕榈滩县Greenacres和Cresthaven附近的军事步道沿线坠毁。飞机从奥斯汀-伯格斯特国际机场飞往巴哈马的北埃卢塞拉机场。NTSB称运营方为Aurora Aviation，商号为Upper Jet，并表示该航班在途中失去雷达和无线电联系。NTSB牵头调查，联邦航空管理局（FAA）协助。⁠26⁠224

这些碎片无法确定解体顺序

找回发动机表明调查人员已能进入此前难以抵达的残骸区域，并不意味着发现了发动机故障。雨水和撞击坑内的积水增加了作业难度；挖掘前，工作人员必须排水并清除危险因素。挖掘于11月4日晚些时候开始——也就是坠机后三个日历日——并在第二天继续进行。这段时间并非三天毫无进展。找回的残骸将送往安全地点检查。⁠5⁠224

关于撞击前发生解体的最明确证据来自撞击坑外。调查人员在1.3至3.8英里外找回了左侧升降舵的大部分，共分为三块。升降舵是尾部一块可活动的翼面，可帮助控制飞机机头上仰和下俯。NTSB成员Tom Chapman表示，碎片距离坠机点之远，足以证明它们在喷气式飞机撞地前已经脱落。但这并不能证明整个尾部都脱落了。⁠10

目前仍存在两种截然不同的可能顺序。升降舵脱落可能导致飞机失控；也可能是飞机已经失控下降，作用于机身的力量将这块翼面撕脱。调查人员尚未确定哪种情况发生，也未查明升降舵在紧急状况的哪个确切时刻脱落。这一区别至关重要：损坏可能是事故原因，也可能是飞机在其他故障发生后所承受影响的证据。⁠10⁠15

前NTSB调查员Greg Feith提出，结构超载以及飞行员试图恢复控制时的操纵可能解释了翼面为何脱落。这是外部人士提出的理论，并非调查机构的结论。机组报告飞机超速，意味着有必要调查这些受力情况；但这并不能证明飞行员操作失误。⁠17

无线电通话记录显示，调查人员面对的是一个以秒计的紧急状况。中午12:47左右，飞机在约35,000英尺高度飞行时，机组报告遇到轻度晴空结冰和中度湍流，飞行高度偏差约700英尺。随后，他们报告有降水，并请求爬升至37,000英尺。获准后不到30秒，一则通话称飞机正在下降，随后发出Mayday求救信号。另一则通话报告飞机超速并在下降；其余内容无法辨认。⁠23

更早之前，空管曾提醒附近有中度降水，当时飞机在约41,000英尺高度——那是飞行的另一个阶段，并非对之后飞行高度的另一种测量。天气是调查的重点，但机组报告的结冰、湍流和降水本身并不能作为事故原因的结论。调查人员尚未确认飞机是否飞过正在活动的雷暴。⁠5⁠153

关于飞机下降速度的描述也应各归其类。CBC报道，无线电通话提到每分钟下降10,000英尺和20,000英尺；《今日印度》报道的数字为22,000英尺。其他报道给出的速度超过30,000英尺，而一项追踪估算称飞机在一分钟内下降了27,000英尺。这些数字可能对应不同时间点或不同测量方法。它们表明飞机下降得非常快，但不能通过合并这些数字拼凑出一个已经确定的重建结果。⁠24⁠1⁠15⁠63

截至11月6日的报道，调查人员尚未找到驾驶舱语音记录器，也无法确认飞机上是否有该设备。公开音频是与空中交通管制的无线电通话，并非找回的驾驶舱对话、警告或操纵记录。这使调查人员难以充分了解飞行员当时的经历。⁠5

家属和社区居民仍在等待

机长是55岁的Jeffrey Gregory，通常称为Jeff。副驾驶是20岁的Nathalia Gadelha Filgueiras。她的母亲Camila Corteleti确认了女儿的身份，并介绍了她的飞行经历；据归于其母亲的报道，她的飞行经验超过1,300小时，并在17岁时取得飞行员执照。⁠145⁠24⁠118

《航空国际新闻》报道称，Gregory持有不受限制的Learjet 60机型等级资格。Filgueiras持有限制性机型等级资格，要求她与完全具备资格的机长（例如Gregory）一起飞行。两人都是认证飞行教员。她的年龄以及这项限制本身，既不能证明机组安排不当，也无法解释事故。⁠15

在11月6日的新闻发布会上，她的父亲Allan Filgueiras表示，空管录音显示女儿一直在努力控制飞机，直到最后一刻。这是父亲对通话内容的解读，并非已经完成的飞行重建。乘客包括企业家Adam Robinson、他的妻子、两个年幼的孩子、孩子们的看护人以及两位家庭朋友。⁠3⁠143

关于地面人员受伤的说法自最初报道以来也有所变化。NTSB调查员Timothy Monville确认，附近一辆车内的一名男子腿部受伤，取代了早期“没有地面人员受伤报告”的说法。官员称地面无人死亡。关于Platts脚部烧伤的单独报道，不应与该机构的通报相加，以拼凑出一个新近核实的受伤人数。⁠23⁠148⁠8

事故现场周边有数百名居民被迫离家。早期报道说约600人被疏散；后来的报道估计有400–600人流离失所，而县政府官员给出的估计约为400人。这些约数并不能证明恰好有200人返回家中。官员正在安排收容、食品、交通、长期住房援助和应急资金；有关居民返家的疏散情况通报中没有确定的时间表。⁠257⁠255⁠153

军事步道最初在Cresthaven Boulevard与10th Avenue North之间双向封闭；后来的描述将受影响路段延伸至Purdy Lane和Alameda Drive附近。受损的水管和其他基础设施可能导致道路封闭数周，有些估计认为至少会封闭30天。目前尚无经核实的重新开放日期。John I. Leonard高中于11月2日停课，另有报道称限制区域内数十家商户停业。⁠86⁠45⁠114

我们首篇报道中的一些不确定之处仍未解决。道路走廊无法确定精确的撞击地址，我们此前提到的Marilyn Drive仍未经确认。Cresthaven、Greenacres和附近其他地名描述的是同一紧急事件；确定的坠机日期是11月1日星期日，而非星期六。基础设施受损已有记录，但仍缺少按服务类别逐项列明的供水或污水服务中断情况。⁠224⁠45

残骸搜寻范围不止道路附近。Ana Escobar说，一块金属碎片刺穿屋顶，落在她家厨房里；警员于11月3日将其收走，但调查人员尚未确认其来源。NTSB另已确认附近屋顶上有飞机残骸，并要求人们不要留存、移动、改动或丢弃疑似残骸。如有可能，请拍照并通过[email protected]报告发现情况，以便该机构安排收取。⁠14⁠10⁠224

NTSB将其残骸搜寻信息标注为初步信息，之后可能更改。预计约一个月后发布初步报告；确定可能原因可能需要一年以上。眼下的任务不只是找回更多碎片，而是要确定它们在紧急状况中出现的先后顺序——尤其要查明升降舵脱落是导致飞机失控，还是发生在失控之后。⁠224⁠19

播出原貌
  1. Investigators recovered an engine section from the buried jet that killed all nine aboard.
  2. Tail fragments found miles away show the aircraft was breaking apart before it struck the ground.
  3. On November 1, we reported nine people aboard, with their condition still unknown. Investigators now have to determine whether a tail-control failure started the emergency or followed it.
  4. The Learjet 60 was flying from Austin-Bergstrom International Airport to North Eleuthera in the Bahamas. It crashed near Greenacres and Cresthaven in Palm Beach County, along Military Trail, shortly before one in the afternoon.
  5. The crash happened on Sunday, November 1. Early descriptions used several nearby community names, but they describe the same emergency. The aircraft carried two crew members and seven passengers. Everyone aboard died, including two young children.
  6. Aurora Aviation operated the flight under the business name Upper Jet. The aircraft lost radio and radar contact while en route. The National Transportation Safety Board is leading the investigation, with the Federal Aviation Administration also involved.
  7. The recovery team had to reach wreckage deeply embedded in an impact crater. Rain and water inside the crater complicated that work. Crews drained water and cleared hazards before excavation could begin.
  8. Excavation began late November 4, three calendar days after the crash. Investigators continued the next day and recovered a portion of one engine. The wreckage will go to a secure location for examination.
  9. The engine section gives investigators another component to examine. The strongest evidence of an earlier separation came from outside the crater: most of the left elevator, a movable tail surface that helps control the aircraft’s nose-up and nose-down movement.
  10. Investigators recovered most of the left elevator in three pieces, between 1.3 and 3.8 miles from the impact site. That distance shows the pieces separated before the jet hit the ground.
  11. Investigators are examining two possible sequences. The elevator could have separated and triggered the loss of control. Or forces on an aircraft already descending uncontrollably could have torn it away. They haven't determined which happened.
  12. Former NTSB investigator Greg Feith suggested structural overstress and pilot inputs during an attempted recovery could explain the separation. That's an outside theory. The investigating agency hasn't reached a conclusion about what started the descent.
  13. The crew’s radio calls describe an emergency that developed within seconds. Earlier in the flight, a controller warned of nearby moderate precipitation while the jet was at about 41,000 feet. Later, at about 35,000 feet, the crew reported light clear ice and moderate turbulence.
  14. The crew described altitude deviations of roughly 700 feet, then reported precipitation and requested a climb to 37,000 feet. The earlier 41,000-foot reference concerns a different stage of the flight.
  15. Less than 30 seconds after the climb was approved, a transmission said the aircraft was descending. A Mayday followed. Another transmission reported an overspeed condition, meaning the jet was flying too fast, and a descent. The remaining words were unintelligible.
  16. Weather is a major focus of the investigation. The crew’s reports describe conditions they encountered, but investigators haven't determined how those conditions affected the aircraft or began the emergency.
  17. The crew described descent rates of 10,000, 20,000 and 22,000 feet a minute during the radio exchanges. Other descriptions put the descent above 30,000, or around 32,000. A tracking estimate described 27,000 feet lost in one minute.
  18. Those figures can describe different moments and different ways of measuring the fall. They can't be combined into one settled reconstruction. What they consistently describe is a very rapid descent, with the crew reporting overspeed.
  19. By November 6, investigators hadn't found the cockpit voice recorder and couldn't confirm it was aboard. The public audio captures transmissions to air traffic control. It leaves investigators without a recovered recording of cockpit conversations and warnings.
  20. The captain was Jeffrey Gregory, known as Jeff, who was 55. His co-pilot was Nathalia Gadelha Filgueiras, who was 20. Her mother, Camila Corteleti, said she earned her pilot’s license at 17 and had more than 1,300 flight hours.
  21. Gregory held an unrestricted Learjet 60 qualification. Filgueiras held a restricted qualification requiring her to fly with a fully qualified pilot in command, such as Gregory. Both were certified flight instructors.
  22. At a November 6 news conference, her father, Allan Filgueiras, said the radio recording showed his daughter trying to control the aircraft until the last minute. The family’s attorney, Stuart Grossman, said 20 NTSB investigators had been sent to South Florida.
  23. The passengers included entrepreneur Adam Robinson, his wife, their two young children, the children’s caregiver and two family friends. Accounts identify his wife as Helen Sharp and name caregiver Anita Maria Cetina and friends Rachael Reed and Charmi Fehr. Some names vary across those accounts.
  24. The NTSB also identified one injured person on the ground: a man in a nearby vehicle who suffered a leg injury. That updates early statements that there were no reports of ground injuries. Officials reported no deaths on the ground.
  25. Stephanie Platts separately said she burned her foot while her family escaped flames and burning debris that reached their property. She said the crash happened yards from her home, and that her family lost the home.
  26. In the November 5 account, Platts was staying temporarily at the Greenacres Community Center. Catholic Charities of the Diocese of Palm Beach was helping her, and a fundraiser had been established to support the family.
  27. Later estimates put displacement at 400 to 600 people. Early accounts described about 600 evacuated from the nearby mobile-home community. Those approximate figures don't show that exactly 200 people returned. The affected community included almost 80 mobile homes.
  28. Residents had no confirmed timetable for returning home in the displacement updates. Officials were pursuing temporary shelter, food and transportation, along with longer-term housing assistance and emergency funds. Businesses were also seeking help.
  29. Military Trail initially closed in both directions between Cresthaven Boulevard and 10th Avenue North. Later descriptions extended the affected stretch toward Purdy Lane and Alameda Drive. John I. Leonard High School closed on November 2, and dozens of businesses closed inside the restricted area.
  30. The crash left a roadway crater, downed power lines and damage to nearby property and infrastructure. Damaged water lines and repairs could keep the road closed for weeks, with some estimates reaching at least 30 days. No reopening date has been announced.
  31. Aircraft debris also reached roofs of nearby homes and buildings. Ana Escobar said a metal piece pierced her roof and landed in her kitchen, less than a mile from the crash scene. Sheriff’s deputies collected it on November 3.
  32. Investigators hadn't confirmed that particular piece came from the jet. Peter DiMaira also described finding suspected tail material at a workplace about 3.8 miles away. Each fragment needs examination before investigators can place it in the aircraft’s final sequence.
  33. The NTSB asks people to leave suspected wreckage undisturbed and arrange collection by email, with a photograph if possible. The agency says people shouldn't keep, move, alter or dispose of it. Small fragments may help establish what happened.
  34. The recovered elevator establishes that a control surface separated before impact. Investigators still have to determine whether its loss began the emergency or resulted from forces during the descent. The engine section and other recovered pieces will undergo further examination.
  35. The NTSB labels the recovery information preliminary and subject to change. A preliminary report was expected in about a month. Determining the probable cause could take more than a year.
