Subject: [AR] CRS-7 Event Timeline
After extensive review of both the NASA and SpaceX video feeds this is an
approximate timeline of events starting at the event.
T-0 Vapor emerges from two locations at top of 2nd stage. Vapor is
ejecting under high pressure. Assumption that vapor is LOX venting.
T+1.8 Fireball appears in vapor cloud. Indicating RP-1 is being vented
simultaneously with LOX.
T+4.51 Fireball extinguished. Vapor still venting at reduced flow
rate. 1st stage continues thrusting.
T+7.28 Second fireball at 2nd stage level of vehicle. Symmetrical
shape of fireball and resulting vapor cloud indicate probable collapse of
2nd stage tanks due to aerodynamic pressure load.
T+7.98 Reduction in 1st stage engines exhaust indicating 1st
stage shut down in progress.
T+8.01 1st stage disappears into vapor cloud. Engines appear to
be shut down, no visible exhaust flame.
T+8.35 Third fireball in vapor cloud. Increase in vapor cloud
size. Probable 1st stage breakup.
T+10.26 Object appears from behind vapor cloud trailing two
fluttering objects. The same object is visible in both the NASA and SpaceX
video feeds. Object is also venting vapor. High probability object is Dragon
capsule, whole or part, trailing collapsed drogue chutes. Object is visible
for approximately 3 seconds in both video feeds. The object goes off frame
in the NASA feed. The SpaceX feed appears to transition to a different
camera. SpaceX did receive data from Dragon after the launch
vehicle failure.
An 8 second event should produce significant data!
