I have a bit of a concern about Le Grand Saut (note spelling of jump in french = saut not sout) after looking at the pics on their website (www.legrandsaut.orrg) of the rig being used. The pic isn't very big, but it looks like an old Javelin, which isn't in itself bad, but the riser sticking miles out of the pack does. Surely at Mach 1.5 you don't want a premature opening, I think it might hurt a little.
