Why is IAF conducting fighter jets' landing & take-off drill at Ganga Expressway in UP?

The IAF conducted take-off and landing exercises on UP's Ganga Expressway at day and night. The exercise, which included fighter jets like Rafale, was organised to assess the expressway's potential as an alternative runway during times of war or national emergencies. It's the first airstrip on any expressway in India equipped to handle both day and night landings of jets.
