Letter: Airliner over Montara?

I was looking out my window towards Montara Beach tonight about an hour ago (5:00 PM) and saw what looked like a 737 flying less than 1,000 feet in a southbound direction over the old Chart House Restaurant. Very strange!  It looked like it was in an approach for the HMB airport.

I called the San Carlos Airport and they didn’t know anything about it. Did anyone else see this?
