French military officer Alfred Groos first produced in 1909 an unsuccessful little triplane. Also in 1909 he produced an equally small monoplane which was named “Quand même” [“Nevertheless”].
A third machine was designed by Groos, a further development along the lines of the “Quand Même”. It wasn’t named after Groos, but was known as the Paul Kaufmann monoplane of 1909.
