KSQL's current controllers have announced that they are all quitting effective tomorrow.
The private corp running the tower lowered their pay by eliminating COL adjustments in the latest contract renewal (a big deal for an airport that is in Palo Alto).
This weekend, with no planning, there will be a completely untowered airport operating underneath the airspace of SFO.
The management is scrambling right now to prevent this, but the best case scenario is that controllers with no experience or local knowledge in training will be thrown into a tower on the busiest day of the week with no colleagues that have done the job before.
