Authorities have reported that crucial braking systems failed to engage during a fatal plane crash on Sunday. An Amazon cargo jet overran the runway at Miami International Airport, colliding with two vehicles and resulting in five deaths.

The National Transportation Safety Board (NTSB) stated that while the aircraft’s wheel brakes were operational, neither the speed brakes nor the thrust reversers were deployed. This was confirmed by Chihoon Shin, the NTSB investigator leading the inquiry.

“There was no indication in the recorded data that speed brakes or thrust reversers were deployed,” said Shin.

Investigators plan to interview the pilots to better understand the incident. Shin refrained from speculating on what might have happened during the landing, emphasizing the need to analyze all parameters before drawing conclusions.

On Sunday, an Amazon Prime Air Boeing 767 ran off the runway and hit a vehicle near the airport. The crash occurred at Miami International Airport on September 6, 2026.

The NTSB revealed that the cargo included mainly contact lenses, weighing approximately 32,222 pounds. There were no hazardous materials onboard.

NTSB Chairwoman Jennifer Homendy provided information about the crew. The captain, aged 55, had accumulated 7,145 flight hours, as stated in his latest Class 1 medical certificate, dated March 31, 2026. The first officer was 37 years old with 2,655 flight hours, according to his Class 1 medical certificate from April 13, 2026.

The crash resulted in five fatalities and injuries to five individuals. Seven of the victims were in a van on airport grounds, which was crushed. The aircraft then breached the airport fence, struck another vehicle, and stopped near a parking area.

This incident raises questions about safety systems and procedures in aviation, specifically relating to braking mechanisms during landing.
