NASA successfully tested the pad abort system for the Launch Abort System developed for the Orion crew exploration vehicle at 9 a.m. EDT. The 97-second flight test is called the Pad Abort 1 test, or PA1. It is the first fully integrated test of the Launch Abort System developed for Orion. The test took place at the U.S. Armys White Sands Missile Range near Las Cruces, N.M.

@ti994apc The actual Gs on this launch were about 16 G. The orion launch abort system is designed to have about 11 g at lanch. 725 kph in 3 seconds. but in this launch it was 725 kph in 2.5 seconds. This is because burntime and sudden accelerations, fuel type and etc. is not an exact science yet. It needs experimentation and fine tuning. But still the astronauts would not normally have a problem surviving this many g. Mainly because of the seats and the direction of the g-forces

@Christian69g Normally it wouldnt get "blown of". The abort system will use three line running down entire vehicle during launch. If the connection is severed on two out of three wires it means that the rocket is exploding and the abort system initiates well before a "normal" rocket explosion reaches the capsule itself.

so but an interesting question is up to what altitude and velocity would this work, in other words not just a launch pad emergency, but would it initiate or simply work by being blown off in a challenger type disaster where the underlying rockets explode at high altitude....ie is there enough shielding on the bottom for it to be blown off and still recover ?

The camera was not shooting enough frames per second to capture it. It even took a few seconds for the secondary camera to locate it. I would estimate that the G-forces were about 3 times to 4 times the force that killed Dale Earnhardt. Its part of the problem when trying to escape from a SRB system like Orion. Solid fuel explosions project their debris for miles so escaping is very challenging. Liquid fuel rockets do not have this issue.

Whoa! How many G's are pulled in this launch?
