54 minutes.

-Autogenous pressurization worked
-Fight termination system took too long to rupture tanks
-Damage to pad not as bad as thought.
-3 engines turned off prior to liftoff, not healthy enough to bring to
full thrust, so shutdown.
- T+27: Engine 19 "lost communications" concurrent with some kind of
energetic event that "liberated" heat shields from engines 17,18,19,20 area.
T+62: Heat shield damage at engine 30, but engine still running.
(cont)
T+85 Things really hit the fan.
Engine 6: loss of comms to thrust vector conrol and from that point,
thruist vector control s=lost for all other engines with it (only 13
engines in inside have gimbals for steering);
-Don't think at this point the "rock tornado" at launch pad caused
engine damage.
-May shorten time to ignite engine and release rocket at pad. This time,
the rocket was held for some time before released to take better look an
engine performance.
