admiral 346 may be quite right about a bent localizer course...
I also think that glide slope extension may not have happened...but we shall see
It always amazes me to find the runway after any sort of ILS. I am reminded of the fine film, "the High and the Mighty"...at the end, the DC4 breaks out of the clouds at night over San Francisco bay...and there ahead are the approach lights...in the film seen so much like a Christian Cross...redemption at the end of a glidepath.
Never take any ILS or instrument approach for granted.
(in "the high and the mighty", the DC4 has an engine dislodge from its mount, causing a fuel leak on a HNL to SFO flight...at night...the captain, who had been going a little crazy wants to ditch, but the copilot (john wayne) slaps some sense into him and they go for the runway...landing with some 30 gallons of avgas)
I hope you see the film some time.
