## Abstract An empirical relation __C__~d~ = 2.7 × 10^5^ R^−1^ is given between drag coefficient, __C__~a~, and Reynolds number __R__, for a captive, nominally spherical, rubber balloon, for the range log~10~ __R__ = 5.1 to 5.8. It is suggested that the drag increases as the shape of the balloon pr
