Telemetry downloaded from Galloping Ghost revealed an 11g pull up,
fuel flow

interrupted on the way up, and then the engine restarted when fuel flow

resumed at the top of the arc.  The aircraft was making 105 inches of
MP(Manifold Pressure) on the way down.

Dave,

Do you think Jimmy could have survived the 11g pull up?

rog

That 11g pull-up would have instantaneously killed anyboby,especially a 74
year old man,not wearing a pressure suit..
That high G-force also probably ripped the pilot's seat right off its
anchoring bolts
.Recall that clear close-up picture of the GG,nose-down,just before
impact,posted in the media of the canopy with no occupant visible.
The shock of the force,pushed Jimmy back and down in the cockpit,killing
him,instantaneously.There just was no way he could have recovered... .

That is counter to what I've read..  Aircraft seats are often designed to a
26G standard because the human body can survive that kind of impact. So to
say that 11g is instantly fatal doesn't quite add up for me.


Matt-


I concur with everything that Matt said in both his posts.  11G's is
unlikely to kill anyone unless sustained for minutes on end, though it will
make anyone pass out quickly.  With practice, some fighter pilots can stay
awake to around 9+ G's - but you have to be ready for it. I personally have
stayed awake with a very sustained 7 G pull in a hornet (with a g-suit), but
have also passed out with a brief 4-g pull that I was not ready for (despite
the g-suit).  Matt is also right that it is not instantaneous even at higher
G's.  You get at least a few seconds running off the energy stored in the
brain cells. Jimmy apparently had enough time to get out a mayday call over
the radio.

The body does not start ripping apart until much higher accelerations are
experienced.  You can do a minute or more without blood to the brain without
lasting damage.
