Remarks: A bad day for Air India! Vigilant passengers onboard "KONARK" bound for Riyadh today at 10.30am averted what would have been a sure disaster! Apparently, a fuel leak from the wings onto the engines provoked sparks and fire from engine1 (extreme right). Luckily, the blaze was doused in the nick of time. All 213 passengers & 15 crew were evacuated through emergency exit chutes of the 744 which was brought to a halt on taxiway A3. Notice the badly charred engine 1 cowling and the wing leading edge! This was the scene at 2pm! Couldn't help the bad weather and heat haze!
