My apologies to the FO if she's as good as you say. And, I agree that the prudent clearance for the Cessna would have been over the field. I've been cleared that way several times.
One thing puzzles me. Why assign 28L, the shorter runway, to the 777 Heavy with a 6 knot tailwind ... unless 889 wasn't THAT heavy.
I think it would wise for SFO tower to issue "Rules of the Road NOTAM or e-mail advisory to all of the local pilots regarding this transition. I subscribe to the FAA's advisories and e-mail NOTAMS
Every time I use the 101 corridor, I look at the TO end of the 28s and, if I see an aircraft there, I tell the controller that I have the traffic in site even if it's not rolling.
In a situation such as this, everyone should be as well informed as possible.
Do you remember when someone tied a big YoYo to the Bufano statue's finger?
