Nearly 850 AI pilots are continuing their strike ignoring stern warning of sacking by the management and the Delhi High Court's decision to initiate contempt proceedings against them.Striking Air India pilots yesterday said they were willing to go to jail and refused to call off their agitation.

The Delhi High Court yesterday initiated contempt of court proceedings against the pilots for their 'utter defiance' of its order on Wednesday to call off the agitation calling it as 'brazen and smacking of sheer arrogance'.The lockout of the airline and invoking of Essential Services Maintenance Act(ESMA) were also being mulled to crack down on the pilots. The AI management ordered the pilots to report for duty failing which it said the airline 'is at liberty to take any action as deemed fit including termination of services'.
