MIAMI, Fla. — What began as a routine cargo flight from Puerto Rico ended in catastrophe Sunday afternoon when a Boeing 767 operating for Amazon Prime Air overran a runway at Miami International Airport, struck multiple vehicles and erupted into a major emergency that temporarily brought operations at one of America’s busiest international gateways to a halt.
At least five people were killed and five others injured, including three critically, according to authorities and reports available as the federal investigation began.
The Federal Aviation Administration identified the aircraft as 21 Air Flight 7598, a Boeing 767-300 cargo jet arriving from Luis Muñoz Marín International Airport in San Juan, Puerto Rico.
The FAA said the aircraft overran the runway after landing at approximately 2 p.m. Sunday, September 6.
The central question investigators must now answer is straightforward but potentially complicated:
Why couldn’t the aircraft stop?
FROM PUERTO RICO TO DISASTER IN MIAMI
Flight 7598 was approaching the end of what should have been a relatively routine cargo operation between San Juan and Miami.
The aircraft was a 32-year-old Boeing 767-300 freighter operated by 21 Air, a North Carolina-based cargo airline performing the flight for Amazon Prime Air.
That distinction is important.
Although the aircraft was operating within Amazon’s logistics network, the flight was operated by 21 Air. Investigators will examine the operator’s procedures, maintenance records, crew actions and aircraft condition as part of the investigation.
The age of an aircraft alone does not establish that it is unsafe. Commercial airplanes routinely remain in service for decades when maintained and inspected according to regulatory requirements.
But the aircraft’s maintenance and operational history will inevitably become part of the investigation.
THE AIRCRAFT OVERRAN THE RUNWAY
The FAA has confirmed one critical fact: the Boeing overran the runway after landing.
What caused that overrun remains unknown.
Investigators are expected to examine where the aircraft touched down, its landing speed, available runway distance, braking performance, thrust reversers, aircraft weight, weather, wind and runway conditions.
They will also examine whether a mechanical malfunction, operational decision or combination of factors contributed.
At this early stage, there has been no official determination of the cause.
That means claims circulating online blaming the pilots, aircraft maintenance, weather or airport infrastructure should be treated as speculation until supported by evidence.
VEHICLES STRUCK NEAR THE AIRPORT
The consequences became particularly severe after the aircraft traveled beyond the runway environment and struck multiple vehicles on the ground.
The collision left a sprawling emergency scene involving the damaged aircraft, wrecked vehicles, fire, leaking fuel and trapped victims.
More than 60 emergency units and approximately 200 responders were involved in the operation, according to Reuters.
The flight crew was among those requiring rescue, while emergency personnel also had to reach people trapped in vehicles.
Images from the scene showed the enormous scale of the response as firefighters, police and aviation personnel converged around the wreckage.
FIVE DEAD, FIVE INJURED
Authorities reported at least five fatalities and five injuries, with three of the injured listed in critical condition.
As the investigation began, authorities had not publicly provided all of the victims’ identities or a complete accounting of where each victim was located when the collision occurred.
For that reason, The Sun Post News will not speculate about whether individual victims were aboard the aircraft or in vehicles until authorities complete notifications and release confirmed information.
Behind every number is a family now confronting an unimaginable loss.
FUEL LEAK ADDED TO THE EMERGENCY
Firefighters faced more than the initial collision and fire.
A fuel leak from the aircraft created an additional hazard and required responders to continue working at the scene for hours.
Airport firefighting operations involving a large commercial aircraft are especially challenging because of the quantity of aviation fuel involved and the possibility of rapidly spreading fire.
Containing that danger while simultaneously reaching trapped victims became one of the immediate priorities.
MIAMI INTERNATIONAL OPERATIONS DISRUPTED
The accident quickly affected air travel far beyond the crash site.
Operations were halted as emergency crews responded and authorities secured the area.
Even after flights began moving again, significant disruptions remained.
FAA traffic-management information showed substantial arrival delays associated with the aircraft accident. An FAA advisory warned arriving aircraft of delays and airborne holding, while airport status information at one point showed delays averaging more than six hours for some Miami-bound traffic.
The disruption underscored Miami International Airport’s importance not only to South Florida but to international passenger and cargo traffic connecting the United States with Latin America and the Caribbean.
A CRITICAL U.S. CARGO HUB
Miami International is much more than a major passenger airport.
It is one of the most important cargo gateways in the United States and a crucial logistical connection between North America, Latin America and the Caribbean.
Reuters reports that Miami ranks third among U.S. airports for cargo throughput.
That makes Sunday’s accident significant beyond its immediate human toll.
The investigation will inevitably attract attention throughout the cargo aviation industry.
WHAT INVESTIGATORS WILL LOOK FOR
The National Transportation Safety Board investigation will attempt to reconstruct the final minutes — and potentially final seconds — of Flight 7598.
Investigators are expected to seek data from the aircraft’s flight data recorder and cockpit voice recorder, commonly known as the black boxes.
The flight data recorder can provide detailed information about the aircraft’s speed, altitude, configuration, braking and other systems.
The cockpit voice recorder can help investigators understand communications and conditions inside the cockpit.
Other evidence can include air traffic control recordings, radar and flight-tracking data, airport surveillance video, weather information, runway inspections, maintenance documentation and physical examination of the aircraft.
The NTSB’s investigative process is designed to gather factual evidence before determining probable cause. Its public docket system ultimately contains the reports and evidence investigators use to reach those conclusions.
AMAZON AND BOEING PLEDGE COOPERATION
Amazon and Boeing have indicated they will cooperate with the investigation.
Amazon expressed condolences following the deaths and said it would support those affected by the tragedy.
For investigators, however, the focus will be technical rather than corporate reputation.
They must determine precisely what happened between touchdown and the moment the aircraft left the runway.
NOT THE FIRST FATAL ACCIDENT INVOLVING AN AMAZON AIR FLIGHT
Sunday’s crash is the second fatal accident involving an aircraft operating in support of Amazon’s air cargo network, according to Reuters.
In February 2019, Atlas Air Flight 3591, another Boeing 767 operating a cargo flight in support of Amazon Prime Air, crashed into Trinity Bay while approaching Houston.
All three people aboard were killed.
The NTSB’s records confirm that the 2019 aircraft was operating for Atlas as a domestic cargo flight supporting Amazon’s Prime Air operation.
There is currently no evidence connecting the cause of that accident to Sunday’s crash in Miami. The two incidents should not be treated as technically related unless investigators establish such a connection.
MIAMI HAS SEEN A DEADLY CARGO CRASH BEFORE
The tragedy also evokes memories of another major cargo accident at Miami International.
In August 1997, a Fine Air DC-8 crashed shortly after takeoff from MIA, killing the three flight crew members, a security guard aboard the aircraft and a motorist on the ground.
The NTSB ultimately determined that improper cargo loading played a central role in that accident and identified deficiencies in operational oversight.
Again, there is no evidence suggesting the 1997 accident and Sunday’s runway overrun share the same cause.
The historical comparison illustrates why investigators must avoid assumptions and follow the evidence.
THE QUESTIONS THAT REMAIN
Several critical questions remain unanswered:
Where did Flight 7598 touch down on the runway?
At what speed?
Were its braking systems and thrust reversers operating normally?
What were the wind and runway conditions?
Was there a mechanical malfunction?
What did the pilots experience inside the cockpit?
And why did the aircraft travel far enough beyond the runway to strike vehicles?
Those answers will not come from social-media videos or early speculation.
They will come from flight data, physical evidence, recordings, maintenance records, interviews and the work of federal investigators.
A TRAGEDY — AND AN INVESTIGATION JUST BEGINNING
For South Florida, the immediate story is one of human loss.
At least five people are dead. Five more were injured. Families are waiting for answers, and first responders confronted an extraordinary emergency involving a large commercial cargo aircraft, fire, fuel and multiple vehicles.
For aviation investigators, however, the work is only beginning.
The FAA’s initial statement confirms what happened operationally — 21 Air Flight 7598 overran the runway after landing in Miami — but not why.
Determining that “why” could take months.
Until investigators provide evidence supporting a conclusion, The Sun Post News will distinguish confirmed facts from preliminary information and speculation.
The Sun Post News will continue following the federal investigation, the condition of the injured and any new findings regarding Flight 7598.
