Photo by Mike Sisemore | C-7044 Sunday, March 24, 2024 Back-Tracking highlights interesting, lesser-known moments in skydiving through the years. These photos are often unearthed from boxes in the attic, old photo albums and dimly lit DZ closets. Please send submissions to communications@uspa.org. Bob Schiermeier wishes he had a little longer of a snivel in the sky over Tahlequah, Oklahoma, in the 1970s.
