STS-3 DEBRIEF

• APU 3 WSB froze [[margin note 1]] during pwr'd flight - shut down APV 3 [[margin note 2]] after single engine pres (~30 sec before MECO)- hydraulic lock-up @ 82% - engine very stable...looked real good. Gordo was able to monitor APU, & shut down - thinks RTLS dump procedure should be re-worked.
• Vibration started at SSME ignition (not SRB)
• noticed wind noise
•white colored debris (left smears on windshield)
•SRB sep - no noise, vibration..just brilliant flash
• ET sep - only clue: 3 red lights going out
• dP/dT alarm: ECR to change limit by -5 or -6 EVAC OUT light
•gang-start of APU's prelaunch worked great

Post-insertion
• theodolite : numbering system bad, tgts hard to see, order bad (start with 3, then work aft). had to use flashlight - it burned out ~15 min. Action to techniques: do we need to do this on ST3-4?
Sun curled [[?]] off some of numbers after 3 days nose sun No deflection in any PLBD case.
• Shoulder brace rel took ~4 sec for t-b gray (Gordo expected 2 sec .... nominal is ~7-9 sec)
