As many as 282 passengers on board a Delhi-bound flight of Air India from Mumbai had a harrowing time today after they were made to sit in the aircraft for over three hours following a technical glitch in the Boeing 777 plane. <br/><br/>The flight, AI 809, which was scheduled to depart from the Chhtatrapati Shivaji International Airport in Mumbai at 11.15 am for New Delhi, took off at 2.34 pm, after a delay of nearly three-and-a-half hours. During this period, all the passengers remained seated in the glitch-hit plane. Air India has ordered an inquiry to find out the glitch in the plane just before its departure.
