Yep, copter was at 300 feet at crash, altimeter was verbally reported by crew to be at 200 feet. At 200 feet, no collision.

Even 100' vertical separation is insufficient clearance.

200 feet was the copter’s assigned elevation maximum at that point in the flight (It does change in different parts of the flight). I can’t remember the plane’s exact elevation but it was reported as in its allowed elevation window above “300ft. Those elevation records are known since the control tower has them, as you know.
