Searching the "black box"

Arrove...
around 1050
we are required to downloading all things and back pack to drop location..
we are given a room for 3 persons .
this mission is to upload all things inside the black box..
its about 3.2 meter.
the day is so tiring...
we need to make sure that inside the room is cleared of rubbish and dust.
everyone could stay nicely..

2 days off...
