Lightning Strikes IndiGo Flight at Kolkata Airport

An IndiGo flight operating as 6E 6068 from Kolkata to Agartala was struck by lightning at Netaji Subhas Chandra Bose International Airport during a fierce monsoon storm on Friday evening, leaving the aircraft grounded on the stand and disrupting operations for dozens of passengers booked on the sector.

Lightning Strike On Stand During Intense Monsoon Storm

According to published coverage from Indian news outlets on 19 June 2026, the Agartala-bound IndiGo flight was parked at an aerobridge bay at Kolkata when a bolt of lightning hit the aircraft’s fuselage amid heavy rain and electrical activity in the area. The Airbus narrowbody, registered VT-IPW, was at aerobridge 56L at the time of the incident, shortly before its scheduled departure for Tripura’s capital.

Reports indicate that the strike occurred while the aircraft was connected to the terminal and ground handling teams were preparing the flight for departure. The region had been experiencing an active monsoon system, with thunderstorms building through the afternoon and evening around the city and its busy international airport.

Initial information suggests that the lightning strike did not trigger a fire or visible structural damage on the stand, but aviation protocols required a full technical inspection before any further operation. The event nevertheless added to weather related stress on an already busy evening wave of flights as Kolkata entered the core of the monsoon season.

Passengers Safely Deboarded As Jet Taken Out Of Service

Local media reports note that around 140 to 150 people were on board when the incident took place, with figures varying slightly across outlets as airlines and airport agencies reconciled manifests. All passengers were subsequently taken off the aircraft through the aerobridge after the crew and ground staff initiated standard safety procedures.

Publicly available information indicates that no injuries were reported among travelers or staff. However, the experience is understood to have been unsettling for those seated on board as thunder and rain intensified outside the cabin in the minutes surrounding the strike.

The aircraft was declared unserviceable pending detailed checks, leading IndiGo to cancel the original departure. Passengers were escorted back into the terminal while the airline arranged alternative travel options and examined the extent of any technical impact on the jet. For many, this meant extended waits and missed onward connections as the evening’s schedule was reshuffled.

Operations Disrupted On Busy Kolkata Agartala Corridor

The grounding of flight 6E 6068 added fresh disruption on the Kolkata Agartala route, a key domestic link between eastern India and the Northeast. The sector typically carries a mix of business travelers, government employees, students and families heading home or onward into Tripura and neighboring states.

Based on flight tracking and airport schedule information, the cancellation forced IndiGo to accommodate passengers on later departures and subsequent days, subject to seat availability. Some travelers reportedly sought rebooking on other carriers or opted for surface transport as monsoon weather continued to affect flights across eastern India.

Kolkata’s Netaji Subhas Chandra Bose International Airport, one of IndiGo’s major hubs, has experienced periodic disruptions during strong convective weather events in recent monsoon seasons. Thunderstorms in the Bay of Bengal region can build quickly, creating short notice constraints on arrivals, departures and ground operations.

Lightning Protection And Safety Protocols In Focus

Commercial airliners are designed to withstand lightning strikes, and events of this kind occur globally each year without causing accidents. Aviation safety material explains that modern aircraft structures and systems are engineered so that electrical energy travels along the outer skin and dissipates, with sensitive equipment shielded and redundant.

Even so, standard procedures require a careful post strike inspection that can include checks of the fuselage, control surfaces and avionics before the aircraft is released back into service. In this case, published reports make clear that the IndiGo jet remained on the ground for detailed technical assessment rather than being turned around for its scheduled short haul sector to Agartala.

For passengers, such inspections translate into cancellations and delays, but aviation specialists frequently emphasize that grounding an aircraft after a lightning strike is a routine, precautionary step. The disruption at Kolkata reflects this conservative approach, prioritising system checks over schedule integrity during an already challenging weather window.

Monsoon Weather Challenges For Eastern India Aviation

The incident has again highlighted the operational challenges posed by the southwest monsoon for airports across eastern and northeastern India. Kolkata’s coastal proximity and the terrain of the Northeast mean that strong convective cells, heavy rainfall and frequent lightning are a recurring part of the seasonal weather pattern.

Historical data on airline on time performance during monsoon months shows a cyclical dip in punctuality as carriers factor in holding patterns, diversions, ground delays and additional spacing between departures. Lightning risk is particularly acute on the ramp, where ground personnel, refuelling operations and aerobridge movements must all be carefully managed during storms.

Travel industry observers note that travellers flying in and out of Kolkata, Agartala and other regional airports through the monsoon typically face a higher probability of last minute schedule changes. The lightning strike on IndiGo flight 6E 6068 is the latest weather linked disruption in a season that is still gathering intensity, and serves as a reminder that flexible planning and real time updates are essential for anyone flying through this busy aviation corridor.
