A minute error in judgment caused the 23-hour-59-minute ordeal involving the AN124 aircraft, which is operated by the US defence forces.

The problem began when the aircraft flying from the Diago Garcia island in the Indian Ocean to Kandahar in Afghan-istan entered Indian airspace by flying within 200 nautical miles of the Indian coastline at 7.35 pm on Friday (see box).

"Had the pilot flown to the left of the path that he took (and got picked up for), the ordeal could have been avoided though he would have had to guzzle more fuel," said air marshal (retd) S Ramdas.

Sources investigating the matter said defence radars picked up the aircraft mome-nts after it entered India's Air Defence Identification Zone (ADIZ).


ID confusion

"The radars picked up the aircraft, which gave out its identity as VDA 4466 (given only to civilian aircraft), but the flight plan suggested that it should be RCH 813 (given only to defence aircraft)," said an IAF official.

Officials elaborated that as per the AN124's flight plan RCH 813 was to operate through Indian airspace on a military mission to Kandhahar on the civilian number VDA 4466.

Aircraft that are assigned a military call sign need to obtain an Air Operations Routing (AOR) number from the Ministry of Defence, something AN124 did not have.

What complicated the matter was that the pilot could not explain why the aircraft was mentioned as RCH 813 in the electronic flight plan.

Experts speak

Aviation expert Vipul Saxena said that keeping in view Indo-US relations and the urgency and importance of operational needs in Afghanistan, defence air controllers could have told AN124 to keep out of ADIZ till Karachi had he given the correct code.

"This would have eliminated the need for the AOR number or for revealing that a civilian aircraft was being
used for military operations, which eventually led to speculations and delays," explained Saxena.

He added that the matter could have been taken up through diplomatic channels later.
