As the video description points out – if you cannot be bothered to check your altitude at least once whilst hurtling towards earth then you should probably give up skydiving all together and stick to a safer hobby such as knitting or bowling.
The skydivers are blissfully unaware of how close they are to the ground and only at the last second do they deploy their parachutes which is made easy by the Cypres fire, an automatic activation device designed for for the less experienced skydiver.
