Shore guy, . .CVR have only very limited range ( 30 min to 1 hour )before getting re-used again. The flight ANC to TPE was 11 hours..no need to pull any tricks there. . .Ironically, if they had pull the CB they would have preserved the interesting conversation that possibly led to the mistake.
As to anyone (pilot or other ) that wants to throw the first stone to the CAL crew make sure that you will never ever make a similar mistake .... .This one gets attention because it was mediatised.. .There were many similar cases in the past, including landing at the wrong airport and/ or on taxi ways...
