Base jumping, for those of you who aren't familiar with this sport, involves jumping from fixed objects. BASE is an acronym that stands for:
Antenna- uninhabited tower like a radio mast
Span- bridge, arch, or dome
Earth- cliff or natural formation
We've seen Bond do it countless times and these BASE jumpers always show up on Extreme sport videos. It is very dangerous but looks like one of the best adrenaline rushes a person could get. They are professionals and I'm sure a lot of training and theory to practice comes into play. You wouldn't want to just jump of a building without checking the wind conditions first.
Bungee jumping is almost like BASE jumping (although it has been around longer) but, after experiencing a short free fall, unlike the BASE jumpers the bungee jumper is safely attached to something and then springs back up. I use the word 'safe' in the loosest of forms because there are plenty of stories of bungee mishaps involving miscalcultions of body weight, bungee length etc. One of the coolest bungee jumping videios I've ever seen was a dual jump off a bridge where both people's heads hit the water below with about as much force as getting a pat on the head. That is pretty impressive considering they jumped from 150 feet above the water.
The video below shows the combination of the two sports. It took me a few times watching the video before I realized exactly what happened and that these two men should probably have a shitload of life insurance.
Both men jump off a bridge connected to each other by a bungee cord. One guy then takes off his parachute, bungees off of his friend who is still gliding, detaches the bungee cord and then throws another chute seconds before he hits the treeline. 'Incredible' doesn't even begin to describe this video.
