An interim report was released yesterday looking into the factors involved in last year’s Sea World helicopter crash. 

Four people were killed and nine were injured in the mid-air collision when a departing helicopter's rotors collided with another coming into land near the theme park. 

The interim report found the departing pilot, who died in the crash, had low levels of cocaine in his system. 

Australian Correspondent Murray Olds told Tim Dower that it would not have been taken in the 24 hours prior to the incident, and that they’re not reading into that particular factor too much.  

He said that there were a variety of factors playing both major and minor roles in the accident, and there’s enough in the report to get people talking.
