This is why batteries need to go in hand luggage!
On 26 April 2014, a passenger checked in four bags for a Fiji Airways flight from Melbourne, Victoria, to Nadi, Fiji, on a Boeing 737 aircraft, registered DQ-FJH. The passenger was a certified remotely piloted aircraft (RPA) operator in Australia. The passenger stated during check-in that there were no batteries in the checked bags, but declared 8 lithium batteries being carried as hand luggage. The bags were screened in accordance with the Aviation Transport Security Regulations.
