Just happened this morning, reporting fatalities. My heart goes out to the families and friends, as well as to the boaters who came to assist. Very sad for the airport community; already talked to one of the flight instructors there and she says it’s really cast a pall over the day.
For the not-so-faint of heart, this one was caught on the LiveATC feed, as there is one for KSQL. It was probably caught at the KSFO super feed as well. The Aviation Clips section there has the details.
