One of the most amazing and shocking stories of 2012 involved a record-breaking dive made by Austrian daredevil Felix Baumgartner, who rode the upper-atmosphere balloon Stratos to 24 miles above the ground, reaching the edge of the stratosphere before diving back to Earth in a spectacular and terrifying free fall; his body actually broke the sound barrier on the way down.
While most of you have seen the original footage shot from the balloon's capsule (part of an ad for Red Bull, who co-financed the stunt), not all of the point-of-view footage captured by seven GoPro cameras – mounted in and out of the capsule and on Baumgartner's pressure suit – has been released to the public.
Just recently, a new HD clip edited together from the combined footage has been posted to GoPro's YouTube channel, and it's every bit as heart-stopping as you might imagine. If the movie Gravity gave you space nightmares, then this clip might be a tough watch too.
So take a deep breath, hang onto something and press play!
