There is no doubt that chopper deal could not have been finalised without the clearance of the then Air Force Chief. The Air Force appears to have relaxed several technical norms and specifications in favour of this deal. The altitude at which such choppers are supposed to fly was reduced and the trial runs which were to take place in India were allowed to take place in the premises of the company. Besides even the bidding process was relaxed for Agusta Westland since as per norms only original equipment manufacturers are allowed to participate. SP Tyagi the former Air Force Chief will be questioned on why several such concessions were allowed in this deal and whether he received any kickbacks or not. Perhaps the biggest political question would be under whose instructions did Tyagi undertake such decisions.
