On the 10th of November 2011, a helicopter of the type EC-130 collided with the mountainous terrain near Pukoo, Hawaii (Island of Molokai). The aircraft was being operated by Blue Hawaiian Helicopters and took of from the Kahului Airport (PHOG).

As there was no air traffic radar surveillance or flight-data of the aircraft, iwi® interviewed four eye-witnesses to reconstruct the flight-path.

The images above show the reconstructed flight path and the analysis of the eye-witnesses.
