An Amazon cargo jet operated by 21 Air overran the runway at Miami International Airport on Sunday, killing five people and shutting down one of the nation's busiest international gateways during the Labor Day holiday peak. The Boeing 767-300, arriving from San Juan, Puerto Rico, crossed a perimeter road at 112 knots before striking vehicles and igniting, drawing more than 200 firefighters and halting all airport operations on a weekend that typically sees peak passenger volumes.

The aircraft and the operator

The freighter was flown by 21 Air, a North Carolina charter carrier that contracts with Amazon's air network. FlightRadar24 data shows the aircraft exited the usable runway surface at 129 miles per hour, a speed that investigators will compare against normal touchdown and deceleration profiles. The plane came to rest near a parking area serving an Amazon warehouse and adjacent businesses, according to the tracking site's analysis.

Weather and runway conditions

Light thunderstorms and gusting winds were present at the time of the landing, per FlightRadar24. The National Transportation Safety Board, which began its on-scene work Sunday, will examine whether the crew touched down within the designated zone and what braking or thrust-reversal actions followed. The NTSB plans a Monday afternoon briefing for reporters.

Amazon and 21 Air respond

Amazon's director of corporate global media relations, Kelly Nantel, said the company is heartbroken and cooperating fully with authorities. 21 Air chief executive Keith Winters issued a statement prioritizing support for those affected and accurate information flow. Neither statement addressed potential operational or financial exposure.

What the market watches next

The FAA's ground stop at Miami International rippled through passenger and cargo schedules during one of the year's highest-demand travel periods. For Amazon, the focus turns to network redundancy, whether other carriers and routes can absorb the lost lift without delaying Prime deliveries. For 21 Air, the investigation's findings will determine liability and insurability. For Boeing, another 767 incident adds to the scrutiny surrounding its wide-body fleet, even as the freighter line remains a profit pillar. The NTSB's preliminary timeline will set the pace for all three.
