And why have advanced landing grounds (ALGs) and roads not been developed in these parts? Because the mandarins sitting in faraway Delhi feared such infrastructure would help the Chinese over-run the region in the event of a repetition of the 1962 border conflict. Indeed, the Indian Air Force (IAF) is still finding it difficult to move men and equipment to the worst affected areas. According Eastern Air Command sources, the mobilization would have been faster had the IAF managed to land AN-32 or a similar large transport aircraft close to Mangan, Chungthang or Lachung.
