This cock up is what happens when children of the Airbus magenta line look out the window and decide to go for it. Wonder where they would have ended up on the Quiet Bridge Visual.

The ILS to 28R was apparently working just fine. TACA 560, another A320, was cleared for the ILS 28R a few minutes before the AC 759 flyby. Sure looks like most A320 operators don't bother with tuning the ILS with a non-ILS FMS approach and it is awkward to view the raw data while getting guidance from the FMS profile.
Listening to the approach control audio in the link posted a couple of times above, AC 759 was coming in on the DYAMD3 arrival, they checked in with NOCAL descending through FL250. They were given at ARCHI join the FMS Bridge Visual 28R. The subsequent controller told other planes to join the FMS Bridge Visual 28R, routing only (I like her style a little better since a couple of planes incorrectly read back the first controller's clearance as 'cleared for the approach').
AC 759 was given depart CEDES heading 270, vectors for spacing. After some vectoring with altitude and speed changes, they were given direct TRDOW, cleared for the FMS Bridge Visual Approach Runway 28R.
Obviously some button pushing to re-intercept the approach at TRDOW, some chances to inadvertently delete a constraint or heal a discontinuity in the wrong place. Still, nothing uncommon at a busy international airport even at midnight in my experience.
