06/05/2005. Remarks by Nico
: "The AC-4 was the most succesfull plane of Flugzeugbau A. Comte,
built in some numbers between 1928 and 1930. This aircraft was
registered CH-244 before Switzerland transferred to the HB-register.
After the war, HB-OTO was still in use at the flying school at Kloten
airfield near Zürich."
