Five people in helicopter crash FIVE men are lucky to be alive after the helicopter they were travelling in crashed landed upside down in the water near Derby in WA's north this morning. The men were carrying out survey work off the picturesque Kimberley coast of Cone Bay when the chopper was forced to make an emergency landing. Staff working at a nearby barramundi farm saw the crash unfold and immediately raced out to rescue the stricken passengers. Jamie Bester, who runs MPA Fish Farms, told The Sunday Times some of the men had to be dragged from the wreckage after becoming trapped. ``There was some sort of emergency but we don't know what," he said. ``The chopper had to do what they call an auto rotation emergency landing. When it hit the water the chopper flipped upside down and the guys were all under water. ``One of (the) guys had to drag them out of the back seat because they couldn't get themselves out. ``We actually saw it go down. Our dive boat was there and responded immediately. ``The guys were prepared to dive if they needed to but luckily they didn't. ``No one was seriously hurt, just cuts and bruises but they are very lucky to be alive. Mr Bester said his 10-man crew brought the injured passengers back to Cone Bay for treatment. They were then flown back to Derby by KAS Helicopters, the company that owns the chopper which crashed.
