    "Nautical Twilight" beginning at 6.20 - at time of crash

    Each twilight phase is defined by the solar elevation angle, which is the position of the Sun in relation to the horizon. During nautical twilight, the geometric center of the Sun's disk is between 6 and 12 degrees below the horizon.
    In clear weather conditions, the horizon is faintly visible during this twilight phase. Many of the brighter stars can also be seen, making it possible to use the position of the stars in relation to the horizon to navigate at sea. This is why it is called nautical twilight.


    It would have been somewhat darker than this with the sun rising behind Mt. Campbell some 4-500 metres higher only 2 km away.
