As investigators look into the causes for the crash of an Air India Express plane flight coming from Dubai at Kozhikode on Friday evening, preliminary information indicates poor weather conditions and a possible late touchdown as possible factors. Early inputs from the airport and air traffic control officials indicate the aircraft touched down way beyond where it should have on the runway. A senior Directorate General of Civil Aviation (DGCA) official said it landed beyond the 3,000-feet mark, when it should have ideally done so no further than the 500-feet mark. Officials are examining whether poor visibility due to heavy rainfall was the reason.
