The Centre has ordered a probe into what could have been the cause behind this unfortunate incident which led to substantial casualties. One of the major reasons cited by aviation experts around the world has been the heavy rainfall over Kozhikode which could have made the landing of the flight very difficult at the airport which has as a tabletop runway. So is the airport's topography the major reason for the mishap?

What makes a tabletop runaway risky?
Kozhikode airport has what is known in the aviation sector as a ‘Tabletop runway’ which is a runway located on top of a plateau or hill and either one or both ends drops into a deep gorge. These runaways are a challenge for the pilot as it requires a very ‘precise approach’ for landing and take-off to avoid issues such as overshooting the runway.
The Kozhikode airport is also located on a hill, and bigger aircrafts such as Boeing 777 and Airbus A330 had stopped using the airport as it was too short. Other examples of tabletop airports include Lengpui airport in Mizoram, Mangalore Airport in Karnataka. Pakyong airport in Sikkim, and Simla and Kullu in Himachal Pradesh.
Mangalore incident
Comparisons are being made between Friday’s incident and the 2010 Boeing 737 Air India Express crash in Mangalore. The incoming flight to Mangalore had overshot the runway while landing and the pilots tried to save the aircraft by attempting to take-off again before running out of tarmac. Unfortunately, the aircraft plunged into a valley below and exploded after the fuel caught fire.
Fortunately, unlike in the case of the Mangalore, the turbine fuel did not catch fire in Friday’s tragic incident.
"In Mangalore, pilots had landed the aircraft in the middle of the runway. Then they quickly tried to take-off again, thereby using thrust and power. However, their attempt failed and at the peak power, the aircraft hit antennas at the end of the runway and dived into the valley," said a senior commander in an IANS report.
He also pointed out that the Mangalore incident was a 'high intensity' one which ignited the on-board fuel, thereby, causing a heavy toll on life.
The Air India Express flight that crashed on Friday was flying from Dubai as part of the Centre’s repatriation flights under the Vande Bharat Mission. Minister of State for External Affairs V Muraleedharan has reached Kozhikode to take stock of the situation where Air India flight (IX-1344) crash-landed yesterday. Civil Aviation Minister Hardeep Puri said, "Two investigation teams of professionals from Air India, AAI and AAIB will leave for Kozhikode at 02.00 hrs & 05.00 hrs. Everyone has now been rescued from the aircraft. Rescue operations are now complete. Injured being treated at various city hospitals."
