Seems like a lot of factual errors in that piece. I can't beleive a helicopter carrying the President was "not in contact with ATC".
Air India does not have A321s.
Finally, VIP 1 is an Indian Air Force 737 and not a 747. The Indian President uses a 747 chartered from Air India for international travel. Domestic travel is undertaken in the Air Force 737.
Notwithstanding all that, a near disaster and a huge scandal averted.
