NEW DELHI: An alert Vistara pilot-in-command saved two aircraft – one which she had just landed and the other about to take off – with 322 people on board from potentially colliding at Indira Gandhi International Airport on Wednesday morning. Captain Sonu Gill had landed the Vistara UK926 from Ahmedabad on runway 29L, closest to the Shivji statue, and air traffic control gave her continuous taxi to Terminal 3 by crossing the parallel active runway 29R. However, an air traffic controller (ATCO) “momentarily forgot” the craft was taxiing and cleared the Vistara UK726 for takeoff from runway 29R.
