Tom Rankin, another member and the film's creator, was posted at that time at the local Navy air base. The 16mm original of the film passed to Dr. Stanley Bittinger, and then to Steve Bittinger, who created this digital version from the original. The film demonstrates early vertical caving techniques and equipment, such as abseiling with a whaletail as well as the more widely used carabiners and brakebars. Craig Bittinger demonstrates an early version of "rope walking" using jumars, and Neil Morris demonstrates the "inch worm" system using ascender knots. Modern vertical caving equipment, technique and focus on safety have evolved considerably since this film was made." _______________________________________________ Texascavers mailing list | http://texascavers.com Texascavers@texascavers.com | Archives: http://www.mail-archive.com/texascavers@texascavers.com/ http://lists.texascavers.com/listinfo/texascavers _______________________________________________ Texascavers mailing list | http://texascavers.com Texascavers@texascavers.com | Archives: http://www.mail-archive.com/texascavers@texascavers.com/ http://lists.texascavers.com/listinfo/texascavers
