I was referring to Triploss when I mentioned Taxi-F, who wrote:-
"When no construction was happening, I've only ever seen aircraft line up directly alongside 28L, which I believe is 28-F (for takeoff on both 28L and 28R), so multiple aircraft on 28-C would also match up with the construction theory. Then again I've never been at the airport around midnight."
Anyhow, a huge accident avoided.
