Summary
Model of Sperry Messenger (U.S.A. 5 airfoil) being tested inside the Variable-Density Tunnel (VDT). The tests were run in early January 1925. Testing was suspended on January 15th "until model and airplane could be brought into closer agreement. Investigation as to the necessary changes was made." The new model was finished in early March and a few more tests were run.
