NTSB in Miami: five dead in a cleaning van. The recorders are in Washington.

The National Transportation Safety Board said Monday that all five people killed when a Prime Air Boeing 767 overran Miami International on Sunday were on the ground, in a cleaning-crew van. Chair Jennifer Homendy, briefing on the field, called the scene “utter devastation.” The flight-data recorder and the cockpit voice recorder were recovered and sent to Washington overnight. A second briefing is on the book for Tuesday. The U.S. desk files the first federal clock, not a cause.

The airplane, a 32-year-old 767-33A operated by Miami-based 21 Air LLC for Amazon, arrived from San Juan at 1:53 p.m. Eastern as Prime Air Flight 7598. It was the tail’s third flight of the day — Cincinnati to Miami, Miami to San Juan, San Juan back. Homendy said it overran runway 30 by about 1,300 feet, struck navigational aids, then hit a 2021 white Ford Econoline van owned by Professional Ocean Service Corp., a contract cleaner. Seven people were inside. Five died. The jet then went through a perimeter fence and struck a Toyota Corolla Cross on the road beyond. Five people were injured, three of them critically. The two crew members on the airplane survived. Investigators have not yet interviewed the pilot or the copilot.

I would describe it in one word as devastating, utter devastation.

“There’s debris everywhere, the van is torn apart,” Homendy said. “The SUV, you can see airbags. It’s pretty extensive. Hard to see, and I’m sure it must have been very difficult for the responders as well.” A go-team of 32 is on site for at least a week. Probable cause will not be named on the grass. The board will look at speed, weather, crew training, 21 Air’s procedures, the Amazon contract — “who does what, what safety provisions might be in any sort of contracts” — and the fact that runway 30 had no engineered material to stop a runaway airplane.

Sunday’s tape still matters. CNN’s review found the pilots never declared a mayday. Video appeared to show the 767 still in the air well down the strip. Experts told the AP the first question is whether it touched down past the usual zone — and if it did, why they did not go around. Homendy would not give a speed Monday. She said the recorders might let her say more today.

Amazon’s Kelly Nantel said the company was heartbroken. Transportation Secretary Sean Duffy told the country to expect delays. FlightAware closed Sunday at 187 cancellations and 266 delays. Two of four runways were dark into Monday. Labor Day traffic sat behind a hull. Names of the dead have not been released. The U.S. desk does not file Amazon. It files five people in a van, a converted passenger jet, and a holiday that already had a $4.15 gallon. The recorders are in Washington. The wreck is still in the grass.
