Eighteen people, including both pilots, were killed after an Air India Express flight from Dubai carrying 190 people skidded off a tabletop runway in heavy rain and broke into pieces on Friday evening at Kozhikode airport in Kerala. The plane, a Boeing 737, overshot the runway at 7.41 PM and rolled 35 feet downslope, said Civil Aviation Minister Hardeep Singh Puri, who has ordered an investigation.
