Νταν Όζμαν: Διαφορά μεταξύ των αναθεωρήσεων

Dan Osman died November 23, 1998 at the age of 35 after his rope failed while performing a "controlled free-fall" jump from the Leaning Tower rock formation in [[Yosemite National Park]]. Osman had come back to Yosemite to dismantle the jump tower but apparently decided to make several jumps (over a few days) before doing so.<ref name="terminal" /> The failure was investigated by the National Park Service with assistance from Chris Harmston, Quality Assurance Manager at [[Black Diamond Equipment]]. Harmston concluded that a change in jump site angle probably caused the ropes to cross and entangle, leading to the rope cutting by melting.<ref>[http://groups.google.com/group/rec.climbing/browse_thread/thread/816f763ab36ceffa/dddc7e3db5defbb5 Dan Osman's Rope Failure Analysis—Possible cause for his death]</ref> Miles Daisher, who was with Osman when he made the jump, stated that the ropes used in his fatal jump had been exposed to inclement weather &mdash; including rain and snow &mdash; for more than a month before the fatal jump, but that the same ropes were used for several shorter jumps on the previous and same day. <ref name="terminal" />
