Sydney-bound Qantas flight diverted due to medical emergency November 20, 2014 - 8:44PM A Qantas flight from Dallas to Sydney has been forced to divert to Los Angeles due to a medical emergency. The A380 touched down at Los Angeles airport just before 9pm AEDT. The plane is expected to spend a few hours at the airport. Passengers from QF8 will be given hotel rooms for the night, arriving in Sydney on Saturday morning. Details of the medical emergency were not known. Unexpected medical emergencies are neither commonplace or unheard of, according to Civil Aviation Safety Authority spokesman Peter Gibson. These things happen from time to time. It's just up to the crew to assess the severity of the situation," he said. It could be anything from a bad stomach bug to a heart attack. The QF8 route between Dallas and Sydney is the world's longest flight at almost 14,000 kilometres. An unexpected pitstop means the crew will change because the flight time is extended.
