The aircraft was a L1011 Tristar. Wet leased from Air Universe of Iceland.The aircraft was trying to enter Indian airspace without a valid authorisation (their overflying permission for their Haj flights between Jeddah and Dhaka had expired on 31Jan) on Feb 01. The aircraft was finally allowed to land at Madras after the pilot reported he was low on fuel after Colombo refused permission to refuel.. .Pilot apparently decied to divert to Colombo as permssion was denied by Indian ATC to continue over Indian Airspace.. .The plane was subsequently allowed to leave on 02nd February evening.. .I do not think Indain Authorities are in anyway to blame. I assume it is the responsibilty of the operator to ensure thepaper work is in order before a flight!
