Chimbu beat me to it, but I would have pointed out also that the Il62 operated from the old Payar lebar airport and not Seletar. The latter was a GA airport after the RAF left it, though Lockeed had a facility there.
It was always know for the Cobras, I lived at Seletar [Hyde Park Gate!] briefly in 1974 before moving to a much more salubrious home [Kenya Crescent}in Woodlands! Two years ago that house was being leased for $10,000-00 a month!
I flew Aerflop Singapore -Moscow-London on a 62 in 1975. Terrible food, worse service, and lots of 'technical' stops for fuel. Quite noisy compared to the VC10.
