This paper presents a detailed analysis of a critical aviation incident that occurred on 21st May 2025, about IndiGo Flight 6E2142 going from Delhi to Srinagar. Flight safety is undeniably the top priority in contemporary aircraft design and operation. Nevertheless, in practice, the performance and safety of aircraft are inevitably influenced by challenging weather conditions, one of which is hailstorms. The aircraft encountered an intense and unpredictable hailstorm, resulting in severe turbulence and causing the plane to make an emergency landing at Srinagar International Airport. Weather conditions, considered as key factors to accidents, can produce interruptions leading to human error and technical failures, despite technological advances. India Meteorological Department (IMD) plays an important role in understanding, monitoring, and forecasting severe weather conditions and phenomena that affect air travel in India. This case study assesses weather patterns and evaluates meteorological conditions through satellite, radar, and Meteorological Terminal Air Report (METAR) observation, which are helpful for pilots as well as forecasters to make prompt decisions.
