An incredible report from my colleague @willguisbond laying out the myriad factors that contributed to January's fatal mid-air collision at Ronald Reagan Washington National Airport — you'll be amazed at what he turned up. It's a long read but well worth your time, and like all of The Air Current's #safety reporting, it's free for everyone to read. #aviation #aviationsafety #dca https://theaircurrent.com/aviation-safety/dca-crash-jan-29-special-report/
