Air India's flight AI-788 with 59 passengers on board took off from Port Blair on scheduled time at 8.15 am.

But shortly before landing at the NSC Bose International Airport here, the pilots noticed cracks in the wind screen of the plane, the sources said.

The pilots contacted the Air Traffic Control and sought permission for priority landing which was granted.

The aircraft landed safely at 10.30 pm, the sources said.
