Many incidents occur on the airside each year due to bird strikes, runway incursions, ground handling incidents, foreign object debris, airside vehicle collisions, airside security breaches, weather-related incidents, and technical issues with aircraft. Vehicles sometimes collide with aircraft, causing damage to the fuselage or other parts of the aircraft. For example, A Boeing 767-300 aircraft departing Delhi was pushed back into a stationary and out-of-service Airbus A320 making both aircraft unfit for flight in August 2017. In another accident, a catering vehicle and a ground-handling vehicle collided with each other leaving a ground-handling staffer injured at Dabolim airport in November 2019. Recently a minor ground collision between two planes was reported at Dubai International Airport in July 2021. One of the aircraft was impacted on the tail by another aircraft during the incident though no injuries were reported.
