Over a mile out? That’s not a near collision.
Let's see, 140 kt final approach speed (161 mph) closing in on an aircraft entering the landing zone. Or, 1.3 miles in 30 seconds. Having worked commercial flights in an FAA Tower, I know that it takes at least 30 seconds for an Embraer E175 to
enter into position for take off. Then the E175 will 'spool up' for departure prior to take off roll.
So now, the arrival crashes into the departure, killing all aboard.
The controller (affirmative action/equity hire) had a serious lapse in judgement and the arrival (no DEI hire yet) did the right thing.
