Sea World helicopter crash report to be released

A report into the Sea World helicopter crash, which left four dead, is set to be released tomorrow. The report includes video footage, 3D computer modelling technology, and interviews from more than 80 witnesses, including crash survivors. Australian Transport Safety Bureau Chief Commissioner Angus Mitchell says the investigation is one of the most complex in the agency’s history. It is almost twelve months since the two helicopters collided. The collision killed four people and injured nine others.
