Oertz V4
   The Oertz V4 (100 hp 14-cylinder Gnome rotary) first flew on March 31, 1912, flown by Henri Wijnmalen. Owing to speed of 172 km/hour that the machine attained on a flight from Bremen to Hamburg (with tailwind !). Wijnmalen got the idea to make a racing variant and to participate in the Gordon Bennett Race in September 1912 in Chicago. Unfortunately there was not enouigh money for the journey to the USA. So the machine never participated.
   The machine was offered to the Preussian Fliegertruppe, but was not bought with the rreason that 'the machine was too fast for normal flyers'.
   In Chicago Jules Vedrines won the race with a speed of 174 km/hour.
   There is a note that one Oertz Eindecker (unknown) type was bought by Krupp for a price of 25,000 DM.
