The army helicopter flying along the Potomac river had deliberately chosen not to broadcast its location to other aircraft or to air traffic control using the common aviation technology called Automatic Dependent Surveillance Broadcast, or ADS B. Had the Black Hawk been using ADS B, like every other aircraft is required to do, tragedy could well have been averted. We've since learned from the National Transportation Safety Board that the military was routinely flying by its own set of rules, particularly around Reagan national, which meant that there had been numerous near misses before this deadly crash.
