I departed SFO a few hours before this tragic accident in a heavy jet.
Our approach to SFO was 'interesting' to say the least. It was the usual, over the field and downwind at 11000 ft, full speedbrake and lots of flap to get down before the inevitable early turn to base.
Cleared for a visual on 28L maintaining own separation from an A320 joining visually on 28R.
High ROD to catch up with the ideal vertical approach path while turning final while watching the other jet.
28L LOC transmitting so followed that, back to Vref+5 early to avoid overtaking the A320 on 28R but end up alongside.
Below 1000ft the (local) A320 flying visually on the right wanders off the centreline towards us. TCAS TA goes bananas but RA inhibited below 800ft. We quickly discuss going around before he corrects back towards his centreline. Look forwards to see four whites on the PAPI's (I had been concentrating looking right at the VERY close A320 for approx 10 secs).
Reduce thrust, set 1000ft ROD, regain profile by 200ft, flare and touch down.
All this after a ten hour flight when it's past 4am on my body clock. How nice it would have been to fly a nice lazy ILS instead.
It's an accident waiting to happen, and it did.
