Mike,

The 700G's is pulled when the aircraft decelerates from >400 mph to 0 mph in
a distance of about 1ft as it hits the ground.

To get back to a more PCB related theme. One phone manufacturer has
specified that devices in their phone must withstand a 1500g shock. That
comes from measured values of deceleration at moment of impact between a
phone and the ground when dropped from ear height.

To get away from PCB's again FYI an artillery shell sees about 20000 G as it
travels up the barrel.....

Regards,
