    This is what I mean by two-phase opening: the lines open first, followed by the fabric.

    When the lines open first, they create momentum for the reserve and help it deploy. As the lines are opening, gravity adds to your initial t...

    green You want the reserve to be as loose as possible, with multiple openings near the air intake, to help it open fast.

    In theory, repacking your reserve for fast opening carries a small risk of breakage during free fall. To minimize these extreme scenarios, r...

    Full line breakage is extremely rare, as long as you fly recent wings and maintain them properly, this should not be a concern.
