Lessons Learned

  • The APS camera exposed almost all frames of film in the air, but they were blurry. After spending some time with the manual, it appears that there's a exposure sensor above lens that sets the shutter speed. Next time we will mount the whole camera against a plexiglas window so that the camera can have full view of the ground.
  • The 50lb-test Kevlar SpiderLine 'weak link' finally held. Jon took the time to put a real knot in it (without use of epoxy) and it held. We'll fly doubles for a while until we're comfortable with it.
