On April 25th, 2010, an Air Force Iroquois slammed into a cloud covered hillside just outside Wellington. Three of the four crew were killed.
Rob Stockley was the squadron leader that day. He's since left the Air Force, but has come forward to shed light on what he says was an avoidable disaster.
While the Air Force is preparing to lay charges against some of it own, Stockley says senior command needs to take a hard look at themselves.
He says he warned his superiors months before Anzac day that tragedy was imminent, and he has some proof to support his claims.
