One of the pilots aboard an Amazon cargo flight repeatedly warned that the aircraft was travelling "too fast" in the moments before it overshot a runway and crashed into traffic, federal investigators have revealed.

The Boeing 767 came down at Miami International Airport on Sunday evening, overrunning the tarmac before colliding with vehicles on a nearby motorway. Five people were killed in the collision, and five others were injured, with two left in a critical condition.

Details recovered from the plane's cockpit voice recorder show that concerns over the aircraft's speed were raised repeatedly for nearly two minutes during the final approach and after touchdown. According to the National Transportation Safety Board (NTSB), the other pilot did not offer a "consistent verbal response" to those alerts.

Flight data shows the crew had been battling strong winds while carrying out an unstable approach into the Florida airport. Automated systems sounded repeated alarms inside the cockpit during the descent, including "sink rate" and "too low terrain" warnings.

The aircraft eventually touched down almost 5,000 feet along the 9,360-foot runway. That late touchdown left the crew with less than half the tarmac's total length available to bring the heavy jet to a complete stop.

Investigators said the pilots attempted a go-around manoeuvre following the awkward touchdown before attempting to brake. The Boeing continued travelling for more than 1,300 feet beyond the end of the runway before crashing into a van on the neighbouring motorway.

All five people who lost their lives were travelling inside that vehicle. NTSB chairwoman Jennifer Homendy confirmed on Tuesday that the van was being used by a cleaning crew employed to work on aircraft at the airport.

The two flight crew members have been identified as 55-year-old pilot Joseph Carroll and 37-year-old First Officer Jaime Felipe Silva Molina. Both men were injured in the crash, but they have since been discharged from hospital following medical treatment.

What we do not know yet is which of the two pilots was voicing the repeated warnings about the aircraft's speed. A complete transcript of the cockpit audio has not yet been released by authorities, though the pilots were interviewed by investigators on Wednesday, according to the Associated Press.

The disaster led to an immediate and total shutdown of Miami International Airport, closing all runways and taxiways while a ground stop was imposed on surrounding air traffic. The NTSB investigation is ongoing, and I'll be following this one — check back for updates.
