Cost maybe ?
By that I mean, the PIC is not to blame here (nor the F/O). His (their) constraints maybe are.
At some point people must "wake up and smell the coffee".
Cheap airline travel does not exist without limitations.
NOR DOES the fact you can't find a downed a/c in 2 hours ! It's "real life". You just can't do it.
Maybe it's "the internet" to blame. Instant "stuff" online, when you need it, right now !
But....within three days. All credit to the Indonesian SAR teams. They did really well I believe.
