In response to a devastating crash involving a Boeing MD-11 cargo plane in Kentucky, the Federal Aviation Administration (FAA) has mandated the grounding of all MD-11 and MD-11F aircraft. The incident, which occurred during takeoff at Louisville International Airport, resulted in the loss of 14 lives when the plane's left engine caught fire and detached from the wing. The aircraft was carrying a substantial amount of fuel, exacerbating the fire's intensity. UPS and FedEx, the primary operators of this aircraft model, have temporarily halted its use while safety investigations are conducted. Both companies have assured that contingency plans are in place to ensure the continuity of critical deliveries, including medical supplies. The MD-11 has been a cargo-only aircraft since 2014, and its grounding raises questions about the impact on logistics and delivery services across the United States.
