Pretty unlucky. Heavy fog rolled in like 15 min before countdown
The rocket was scheduled to be launched at around 6:30 a.m., but since a number of troubles were found in valves of liquid oxygen tank etc, work continued with the aim of launch until 0:30 pm. However, it was decided that safety could not be secured because a ship entered the warning area on the sea, and it was decided to aim the launch after 3:45 pm.
