A coroner says it will be a "massive task" to piece together what happened in a fatal mid-air crash which killed two teenagers and a helicopter pilot in 2008.
Coroner Ian Smith today reserved his findings at the end of an inquest into the crash at Paraparaumu Airfield north of Wellington.
Those who died were plane pilot Bevan Hookway, 17, and the occupants of a Robinson helicopter - student pilot James Taylor, 19, and the experienced rescue pilot who was testing him, David Fielding, 30.
Mr Hookway was flying solo in a Cessna light plane while Mr Taylor was doing his final flight test when the aircraft collided on February 17.
Coroner Smith said circumstances were complicated and he faced a "massive task" in reaching his findings.
