The crash killed three Britons and a South African on board the four-seater Diamond DA62, the Dubai Civil Aviation Authority said. The UK registered plane was on a mission to calibrate terrestrial navigation systems at the airport when it crashed about 5 kilometers south of the airport. The crash was due to a mechanical fault, Dubai Media Office said. The airport said it halted flights from 7.36 p.m. until 8.22 p.m. local time over the crash. “All operations at the Dubai airport are running smoothly after a slight delay and diversion of some flights as a precautionary measure to ensure security following a minor incident involving a small plane,” the media office said. Dubai International Airport, home to the long-haul carrier Emirates, is the world"s busiest airport for international travel.
