My fading memory seems to recall a KLM DC 8 landing at Changi instead of Paya Lebar when I was stationed there in 69/70. Runway direction pretty much the same I remember.
Also happened in 67 with an Air India 707 (or similar) landing at Changi. (what happened to Paya Lebar btw?)
Also at Seletar in 67 an erk wandering from East to West camp on the road across the closed runway at night was scared s**tless when a Javelin from nearby Tengah screamed over his head and plonked down on the unlit runway. Reputedly so short of fuel he couldnt make it to Tengah, but still a good effort landing with on the black bit in the middle of the not quite so black bit!
