Could someone put this missing glide slope in perspective ?

Just how important is it to a landing in darkness with little or no
visibility ? What other instruments/information would have been
available to the pilot to help him stay on track to the runway ?

Is it plausible that the missing glide slope would have resulted in the
plane being much lower than it should have been in its approach ?

How common is it for the glide slope to be inoperational for airports
that handle 747s on a daily basis ? Is this a no-brainer for pilots when
it is missing, or does this require a lot more attention ?
