For three consecutive days, rescuers never give up ,even a slight&slim chance, to find the survivors.
(=What chance is there of anybody being found alive in 24x3=gold good chance of survival 72 ?)
For 3 long days, rescuers did not even slow down in light of the possibility that the victims might remain alive.
