.....there was a shameful lack of precision nav aids.
In the 21st Century it is unforgivable that accidents like this should continue to happen. Especially at a capital city international airport due to inadequate landing aids.
And to many others that have commented on non-precision approaches here:
My only comment is if you don't see the runway/airport at minimums, simple; go around. Nothing wrong with non-precision approaches that a little training can't take care of.
