-Door removal (Completed 10 April 2012) Apollo
-Retrieve witness plates(Completed 10 April 2012) Travis and Jodi
*Note-These five plates were put in place just before BSC8 was closed up and pumped down. 
Locations: 
#1-GV1 nozzle=Witness plate 5 (6 particles on whole plate)
#2-GV3 bellows convolution=Witness plate 4 (11 particles on whole plate)
#3-YBM bellows convolution=Witness plate 3 (8 particles on whole plate)
#4-Face of quad optic/ACB face=Witness plate 2 (5 particles on whole plate)
#5-Center of BSC floor=Witness plate 1 (8 particles on whole plate)
They should give us some idea of the quantity and quality of particulate that gets moved around during one pump down/venting cycle.
