How can you pass 5 mile and be fully configured when you’re instructed to be at 180 knots to 5 miles?
And... Is that 5 from threshold or 5 from DME? In SFO that's a pretty big difference. Remember, glide slope was offline and they were on a visual approach, so the crew could be using SFO VOR as DME reference instead of the terminal DME.
