We had this experience last Sep 4, 2011 at DANAO Extreme Adventure.
It was really a great experience (terrifying at first) but months of internalizing has prepared me for it. :)
I floated thru the air and I forgot to scream, I really cant scream as oppose to John who scream his heart out. ^-^
Plunge: a canyon swing adventure attraction mounted over a 200 meter high and 300 meter wide gorge. A person would have to do a 45 meters free fall before being launched on a pendulum swing measuring to a hundred meter diameter. Cable has a maximum working load of 5 tons. Now longer (70 meters) more fear some.
One has to literally plunge to an open air for about two seconds, the plunger will all be defenseless, feel nothing and left all alone.
This extreme adventure cost P700/pax. Hope the video will play well.
