Goods train laden with coal derails near Ambala

The Indian Air Force (IAF) has retired its long-serving MiG-21 fighter jets, reducing its already low number of fighter squadrons. Despite its successful track record since 1963, the MiG-21 has faced challenges with its engines, leading to crashes and deaths. To replenish its squadrons, the IAF intends to introduce a mix of domestic and foreign fighter jets.
