Why did the 4-5 fire fighters go to the bus (tail section) without a handline?

为什麽4-5名消防向大巴士（飞机尾部）而没有携带手持水？

The four personnel on the handline would have been better used with two on the handline and two doing rescue and relocating the injured away from the dangers.

四位元消防手持喷头的情况，可以修正为两位手持喷头，另两位从险境中将伤救出。
