The global delivery service, FedEx, says it has canceled its order for 10 huge Airbus A-380 cargo planes.
FedEx is the first prospective customer of the troubled A-380 to end its order.
FedEx officials say they will instead buy 15 Boeing 777 cargo aircraft.
The cargo company says global demand for air cargo and express services is growing rapidly, and it needs new planes to keep up.
The cancelation comes after the newly-developed A-380 fell two years behind in its delivery schedule.
Airbus officials have blamed wiring problems for the delays.
