D.F.W. No. 154 under guard to keep inquisitive youngsters away. Points to note are the D.F.W. logo just behind the guard and the serial application to the rudder. No. 154 was at Brooklands by 17 March 1914. These photographs are of the incident of 31 March, 1914 when Lt C.H. Collet, RMA, attempted to fly from Portsmouth to Wick, but force landed at Jenning's Farm, near Donna Nook, Lincs. The front cockpit appears to have the supplementary fuel tank that was fitted for the attempt.

In addition to the crashes, there were always taxi accidents, a particular hazard for these early aircraft without brakes. Here a DFW Mars biplane has experienced a close encounter of the worst kind with a Taube.

DFW Mars Two-Seaters
The Mars monoplane was designed and built in 1912, the same year as the Mars-Buchner biplane was built. The standard Mars biplane was developed from the Mars-Buchner biplane with a more robust wing cellule. The Mars monoplane and biplane were similar in appearance other than their wings.
The Mars monoplane originally had a four cylinder engine but most had a six-cylinder, 100 hp Argus, Daimler, or NAG engine. The wings were designed to fold. Most used wing warping for roll control although at least one had a modified wing that featured ailerons.
The Mars biplane also originally used four-cylinder engines like the 95 hp NAG, Daimler G4F, and others. Once more powerful six-cylinder engines became available the later production Mars biplanes used these more powerful engines. The wing cellule was a robust, three-and-a-half bay design that was also designed to fold the wingtips for storage in tents while in the field.
Both the Mars monoplane and biplane were two-seat aircraft that could be used for reconnaissance and training. In 1913 a Mars biplane was flown for the Turkish side in the was against Bulgaria, and a long reconnaissance flight was flown with Captain Kemal Bey, later to become president of Turkey Kemal Attaturk.
Small numbers of the Mars biplane were flown at the front during the early part of the Great War, and it is possible that Mars monoplanes were also used at the front. Certainly both types were used for training before and after the beginning of the war.
