Something doesn't seem right here.
At 2:30 in vid related, Burbank Tower told the pilot to keep his squawk (iow, as previously assigned, not 1200). Then talking to Van Nuys Tower, he said he wanted to be handed off to Approach, so he would have had no reason (and not be permitted) to change it. He reads back the handoff frequency correctly.
SoCal asks him to IDENT at 3:57 and then at 4:03 SoCal says he was on a 1200 (VFR) squawk which makes no sense, unless he improperly changed it (why?), or the controller saw the IDENT of another aircraft. Even under normal circumstances, this would be unusual.
These recordings raise more questions than they answer. The raw ADS-B data, if any was captured publicly might be interesting.
Spoopy.
