Closer to Human Flight
negativeblue writes "Dropzone.com has (had) a story about the preparation of a man (Jeb Corliss) who prepares to land a wingsuit without a parachute. If you don't know the current abilities of parachutes, now-a-day, you should do your research. Basically airfoils, they can perform close to an airplane wing (high performance turns and lift)."
I don't think most people know the abilities of modern day parachutes. It has been a few years ago when I left the skydive scene, but at that time huge progress was made using new materials and designs. Modern parachutes might look like ordinary square parachutes, but there are some important differences: so-called 'zero-porosity' fabrics and high-tensile fibers, combined with elliptical shaped canopies result in very efficient parachutes. Some of those can be made *extremely* small (like the Icarus mentioned in the article). Smaller canopies result in higher speeds, but also in higher descent rates. Some of those canopies cannot be landed safely without diving for speed first (using so-called 'hook-turns' or 'front-riser' turns). Seeing somebody land a high-performance parachute is rather spectacular because of the speeds involved. The gap between flying the smallest of those high-performance parachutes (and the technique needed to safely land them) and flying a wing-suite is not that big anymore, and that is what the poster meant to say.
