Some interesting comparison tests were recently made between the new LB-5 and the NBS-1 under the direction of Lieut. Odas Moon, Air Corps, who is attached to the 20th Bombardment Squadron, Langley Field, Va., for this particular work. A climb test was performed with Lieutenant Moon flying the LB-5 and Lieut. A. H. Johnson and Lieut. Ward J. Davies each flying an NBS-1.
