That is my recollection. What I don't remember was when the started the simulcast. As I have mentioned before, I was on a taking-off plane at LAX when the airport was shut down. The plane aborted, and we went to the gate and were herded out of the airport. Back in my car, I went to KFWB and they were well into full coverage and it was from their newsroom at that time.After so many years, my memory might be fuzzy, but I seem to recall some, if not all the CBS stations in LA simulcast with KNX or KFWB during the early hours of 9/11.
About an hour later I got to Glendale and became more concerned with KLVE-KRCD-KSCA-KTNQ. We were taking feeds from WADO in New York, which then still had an actual news department.
