US Army Blackhawk (H-60) helicopter is not Boeing-made, but same theme.

AP: The Federal Aviation Administration said the midair crash occurred before 9 p.m. EST when a regional jet that had departed from Wichita, Kansas, collided with a military helicopter on a training flight while on approach to an airport runway. It occurred in some of the most tightly controlled and monitored airspace in the world, just over three miles south of the White House and the Capitol.

Another very weird one to kick off the year. How does a military helicopter crash into a commercial flight coming into land at a major airport?

We already know the official report: Human error - in that they didn't pick up on the AI error - aka: falling asleep at the AI wheel, as you do. Actually, nobody's fault.
