Those guys went to work that day with the best intentions. They've been thoroughly let down and people should be ashamed this occurred. Their deaths were entirely preventable. It's not rocket science - poor serviceability, low flying rates, inadequate training, lack of focus and poor command will kill people. Only fools believe otherwise. Unfortunately it's the guys and girls at the pointy end, doing their best, that pay the piper. The report only proves what people knew already. My most sincere condolences to their families and friends.
