Alliance Air Flight 7412 departed Calcutta (Kolkata) at 06:51 on July 17, 2000, for a flight to Delhi, with stops at Patna and Lucknow. The crew had been cleared to land at runway 25 at Lok Nayak Jayaprakash Airport at Patna when the pilots requested a 360-degree orbit due to the flight being high on the approach. Permission was granted and a left turn was initiated. During the left turn, the aircraft stalled. The plane then grazed a few single-storied houses in a government residential housing estate and crashed in a government residential colony behind Gardani Bagh Girls School at Anishabad, which is located about 2 km southwest of the Patna Airport.
