• plume changes shape ~ 64.7 sec (coupled with LH2 pressure - decrease in rise rate)→ evidence of leak in LH[subscript]2 tank (could have 4#/sec leak that wouldn't have been detected up until then)

• ~72 sec, lower aft attach point fails (RGA data)[data goes through upper aft attach point]

• R SRB into tank caused LO[subscript]2 tank rupture

LITTLES: scenarios
① case membrane burn through (from flaw in inhibitor)[wouldn't see increased P[subscript]c

② LH2 leak (4#/sec = .18" dia not detected)(review x-rays for flaws in tank that loads could have ruptured)

Transcription Notes:
- 2 in"LH2" should be a subscript - 2 in "LO2" should be a subscript - c in "Pc" should be a subscript
