First rule in aviation, never assume!
Of course this crew looked at all options and deemed
it safe and prudent to continue, what irks is the rationale
of some with 4 jet (not 'quad'... please)
experience is rather blinkered, and quite frankly pompous!
Some need to read up on risk management methinks.
Safe to continue, but 'absolutely safe'? , as I said, doubt it.
