Some future tests of the weak equivalence principle (WEP) with laboratory-size proof masses are likely to be conducted in freefall conditions in order to improve the test accuracy substantially. Some years ago the authors of this paper proposed to test the WEP in a vertical freefall inside a capsule released from a high-altitude balloon. The estimated accuracy in testing the WEP, with a 95% confidence level, is a few parts in 1015 in a 30 s freefall. When compared with other proposed orbital freefall experiments and ground-based tests, the vertical freefall retains some key advantages of the former without some of the disadvantages of the latter. Moreover, a two orders of magnitude increase in the accuracy of testing the WEP could be achieved with an affordable experiment that allows us to recover the detector and repeat the launches at short time intervals.
