A 21 Air-operated jet overshot the runway at Miami International Airport and struck multiple ground vehicles in an incident that resulted in fatalities. The accident prompted Amazon to suspend its contractual relationship with the cargo carrier pending investigation. The move reflects tightening risk management practices among major logistics operators, particularly in light of heightened scrutiny of third-party carrier safety protocols and incident response mechanisms. Amazon's decision underscores the competitive pressure within the express logistics market—carriers that experience operational disruptions due to safety incidents face rapid client attrition.
