Yes they definitely should have seen and heard each other, but then again when the Airbus started it’s takeoff roll, they would have been maybe 6 miles apart? I would have expected both to have their anti-collision lights on. My bet is one of these aircraft was on the wrong frequency. I’ve done that once before and nearly had the same result.
