The Wright Martin TT was one of the first military airplanes of NEIAF. Lots of problems occurred with these aircraft.
Initially they were equipped with floats, but the Hall-Scott engine didn't have enough power for this configuration, so the floats were soon replaced with wheels.

Float plane Glenn Martin TT. (1914-1917); later equipped with a wheel under carriage.
