Reserve Parachute Training & Testing via our onsite Zip Line… gives our students & pilots the opportunity to exercise this emergency option. We have found that, on a GOOD day, 1 in 10 reserve parachutes are not operational. For numerous reasons that range from improper installation; shifting of components rendering it undeployable; deficient pilot understanding / technique. “Borrowed, antiquated, ebay & friends” are big yellow flags. Annual inspection & repack by a reputable individual/center is pivotal. ~ Marc Chirico / Seattle Paragliding (206) 387 3477
