Smoke in cockpit of Dreamliner B787 plane

Smoke was detected in the cockpit of Air India's Dreamliner B787 plane when it was on the way to New Delhi from Kolkata but it landed safely at Indira Gandh International Airport.
Air India flight AI 701 took off at 1730 hours from the Netaji Subhas Chandra Bose International Airport for Delhi yesterday.
"However, when the aircraft was mid-way, the pilot detected some fumes and smoke in the cockpit. But, it was confined to cockpit only as the crew did not report any such smoke in the cabin. The crew then declared emergency onboard and aircraft was steered to Delhi after taking some additional safety measures," airline sources said today.

The plane made a precautionary but safe landing and is now grounded here for a thorough inspection, the sources said.
Initial investigation into the incident suggests some glitch in the aircraft's cabin air compressor as the cause of detection of smoke and fumes, they said.
