It doesn't matter that 'we know nothing about aviation', the bottom line is
that as punters, whether you think we are entitle to or not, we damned well will
expect that a) If all the navaids and hi-tech landing aids at an airport do conk
out then YES the drivers of a modern highly automated robotic super jet can
still get everybody down in one piece with no drama, but that b) NO they should
damn well never be asked to prove it absent earthquake or other calamity, and
especially not just because one of the worlds busiest airports can't be bothered
to find a way to provide the services we expect to be there to make our flights
safer.
KWH, I hope that you never want to fly into any of the airports within 250 NM of where I live, as not one of them has a GS.
