Test Stand Information
4/7/04 Optical and vibration test stand information. Based on attempmting to meet the NASA test Specs. -Current thought is the stand is not needed based on information available in references.435073.ps, 435074.ps, 435076.ps, 435077.ps, 435078.ps, Assy_Drawing_435079.ps, 435080.ps, 435081.ps, 435082.ps, 435083.ps, 435084.ps, 435085.ps, 435086.ps, 435088.ps
