As one completes the immigration and security checks at the Tribhuvan International Airport (TIA) and passes through the boarding gates, one gets amused on why is there another set of security checks, just next to the runway, before boarding an Air India flight to Delhi? The two feet tall ladder is fixed to a wheeled iron chamber where one gets their hand/cabin bags checked. The practice had begun after Indian Airline flight IC 814 enroute from TIA Kathmandu to IGIA, New Delhi was hijacked by Pakistan backed terrorists.
