A helicopter crash in Cairns, Queensland, resulted in the pilot's death and injuries to two hotel guests. The incident occurred around 1:50 AM when the helicopter collided with the roof of the DoubleTree by Hilton hotel, causing a fire and prompting the evacuation of approximately 400 people. The pilot was the sole occupant of the helicopter, which Nautilus Aviation confirmed was on an 'unauthorized' flight. Eyewitnesses reported the helicopter flying unusually low before the crash, which created a significant hole in the building. Two guests suffered smoke inhalation but were later discharged from the hospital. Investigations by the Queensland Police and the Australian Transport Safety Bureau are ongoing to determine the circumstances surrounding the crash.
