An Indigo flight carrying West Bengal Chief Minister Mamata Banerjee hovered for over half an hour in the city sky before landing at the Netaji Subhash Chandra Bose International Airport reportedly due to technical reasons, prompting Trinamool Congress to allege that it was a conspiracy to eliminate the party supremo. Trinamool leader Firhad Hakim, who was accompanying Banerjee in the flight alleged that the plane was flying short on fuel but the ATC kept the flight on hold. Indigo however clarified that the captain of the flight, at no stage, declared a fuel priority or emergency. It also said misinterpretation by the ATC controller had led him to instruct fire engines and ambulances to be stationed at Kolkata airport. Meanwhile, Minister of State for Civil Aviation Jayant Sinha assured Parliament that the DGCA will probe into how three flights to Kolkata including one with Mamata Banerjee on board reportedly had low fuel.
