Tower closes at 1000 UTC by ERSA. Incident at 2305L?
Also
if it became a night visual approach, descent below LSALT is permitted if when in circling area.
"Reference to circling area in this section
includes the circling area for the category of aircraft
or a higher category where the limitations of the
higher category are complied with."
..so 6.94 NM is permitted, and web track appears shows aircraft within this. (It goes off the range)
Weather was crystal clear.
Damage is been done in the media though.
