The Air India plane took off at 4:40 PM from Varanasi's Lal Bahadur Shashtri International airport for New Delhi, but just after 15 minutes of flying it had to land back again at the airport due to detection of technical snag in the aircraft by its pilot, said Airport Manager K P Singh.
The technical fault of the aircraft was rectified by the engineers and the plane took off at 6 PM, said Singh.
