Key safety system off in Army helicopter that collided with American Airlines jet, senator says

7. What's going to come out in this investigation

is that the issues on board the Blackhawk that led to this crash were systemic and it was pure good fortune that this didn’t happen earlier. My guess is that if you look at all the rules broken and guidelines ignored by this Blackhawk crew you would find some combination on a large fraction of similar operations by military helicopters around the DC area. The normalisation of rule breaking/bending is a constant threat to safety and it always goes hand-in-hand with the justification that nothing bad happened the last time. And then it does and we realise how close to edge we have been for a long time.
