I was spotting at Changi Airport yesterday night with one of my friend. I saw a Singapore Airlines A340 took off but when he was at about 800 to 1000 feet, i saw the rear part of the 4 engines are all glowing red. I am suprised to see this happen but at the same time, i am curios. Are the engines too hot or are there some other reasons?
Maybe this is one factor that lead passengers to think there was fire in the engines in the previous cases?
Thanks a lot for the time.
