DC air crash tragedy - can we get past the politics?

At Reagan National Airport in Washington DC, we have seen a major tragedy with the mid-air collision of a passenger airliner and a military helicopter. Almost immediately, the public space has been awash with a blame game. Trump kicked it off, but the mainstream media chose to make his DEI comments the main story. Others hit back, saying the crash was Trump's fault for actions taken in his first week. In the mean time, we're left asking what actually happened, and what will be the grown-up lessons to be learned from it, so that the personal tragedy of all those whose lives were lost, and all those who now mourn them, at least may not have been in vain? Let's discuss.
