New Delhi, Aug 4 - A Jet Airways flight made an emergency landing at the Indira Gandhi International Airport here Tuesday following a technical snag in its undercarriage wheels.

The pilot of Flight 9W 2601, which was on its way from Delhi to Vadodara, detected problems in the undercarriage wheels around 40 minutes after the take-off and made emergency landing by around 6.10 p.m., airport officials said.

'The wheels are supposed to retract after taking off. But there were some technical problems so that the wheels did not go inside. The pilot could have continued flying, but it is not advisable as unretracted wheels cause lot of air resistance to the aircraft,' V. Soma Sundaram, executive director of Airports Authority of India (AAI), told IANS.

The flight landed smoothly and all passengers are safe, he said.
