A thorough investigation into the serious breach of communication between seven planes and the Kolkata air traffic control two days ago has been demanded by CPI(M) leader Sitaram Yechury, who said the incident had jeopardised passenger safety and security.
Yechury, in his capacity as Chairman of the Parliamentary Standing Committee on Transport, Tourism and Culture, which covers Civil Aviation too, wrote a letter to Civil Aviation Minister Praful Patel.
"I am sure you will agree with me that this is a very serious matter not only jeopardising air traffic control, with all its horrific consequences, but also has serious security implications for the country," Yechury said in the letter.
He said that in the background of the 26/11 Mumbai terrorist attacks, such an incident "requires a probe thoroughly from all angles".
Yechury urged Patel to "treat this matter seriously and order an urgent thorough enquiry.... Given the gravity of the situation and the urgency."
On January 27, communication links between seven planes, including those flying into Kolkata, and the air traffic control (ATC) at the Netaji Subhash International Airport was disrupted for an hour.
The planes included a Bangkok-Kolkata Jet Airways flight and an Emirates Airways plane.
