A technical glitch at Delhi’s Indira Gandhi International Airport caused significant disruptions, affecting over 800 flights due to issues with the Automatic Message Switching System (AMSS), which is vital for air traffic control. The Ministry of Information Technology confirmed that the problem arose during a software upgrade and ruled out any possibility of a cyber attack. Airlines, including IndiGo and Air India, reported delays as air traffic controllers resorted to manual flight plan processing. Passengers faced extended waiting times amid long queues. This incident underscores the critical need for robust technical systems and contingency plans in India’s aviation infrastructure, especially as air traffic increases post-pandemic.
