Went in to BSC6 while Apollo crews are hanging the door.
There were following things left in the chamber, and all of them were removed:
I didn't see 1" witness mirror on the floor but I don't know if it's supposed to be there (it was not on Jody's check list either). Witness plates were there and of course they were left in.
One thing to note: Things are dirty. I was able to see lots of dust particulates on the witness plates on the floor as well as TMS mirrors (see pictures). ETM was better, but I was able to see some glints when I used a flash light.
I wiped the floor, about 1sqft in front of ETMY and maybe 2sqft right under TMS using Vectra wipes with alcohol, but it was not clear if I was removing dust so I stopped and told Apollo people to close the door. The wipes I used to wipe the floor was saved but I don't intend to do anything with it.
Anyway, as far as I'm concerned, BSC6 is ready to be pumped down.
