According to sources, the visible range at the airport dropped to 25 metres, causing widespread anxiety among travellers and the airport staff. The situation started deteriorating at 6 AM when visibility decreased to 50 metres. Despite efforts to maintain normalcy, the situation worsened after 7 AM as visibility further plummeted to 25 metres.

This raised concern among the airport staff about the feasibility of take-offs and landings in such conditions. Several fights took extra time to land due to fog. Airport authorities closely monitored the situation and tried to manage the crisis. Flight schedules were reevaluated and efforts were made to provide timely updates to passengers.

The airport authorities contemplated using modern CAT (Category I) lights to facilitate regular flight operations. Sources said that measures were taken to address the issue with a focus on maintaining the normalcy of flights on a war footing. The use of advanced CAT lights helped in smooth air traffic operations. While the situation was being closely monitored, it was anticipated that the visibility will improve rapidly as the morning progressed.

The deployment of modern technology and vigilant efforts by authorities were primarily aimed at restoring regular flight operations at the Kolkata airport and ensuring the safety and convenience of passengers.
