1930 Bristol Airport International Touring Competition Aircraft medal in case given to pilots & crew
The International Touring Competition in 1930 (French: Challenge International de Tourisme) was the second FAI international touring aircraft contest, that took place between July 18 and August 8, 1930 in Berlin, Germany.

Germany organized the contest, because the German pilot Fritz Morzik won the previous contest in 1929. The regulation based upon the FAI rules, but details were worked out by the German Aero Club. The international Sports Committee was headed by the German Gerd von Hoeppner.[1] 98 crews applied, but eventually 60 aircraft entered the Challenge in 1930, from six countries: Germany (30 crews), Poland (12 crews), United Kingdom (7 crews), France (6 crews), Spain (3 crews) and the Swiss (2 crews). In the British team there was one Canadian, and in the French team – one Belgian.[2] It was the first major international event in which the Polish aviation took part, with second most numerous team in addition, equipped with own design aircraft.[2] This time, Italy nor Czechoslovakia did not participate. In the German team there was first of all Fritz Morzik – a winner of the Challenge 1929. Among the British team, there were pilots: Captain Hubert Broad (2nd place in 1929), the Canadian John Carberry (3rd place in 1929) and two women: Winifred Spooner and Lady Mary Bailey.[2] In the Spanish team, there was prince Antonio de Habsburgo-Borbón. Many other known aviators of that time took part in the contest as well. The contest was open on July 18, 1930, at Berlin-Staaken airfield.[3] It consisted of two parts: a circuit over Europe and technical trials. Since one of the aims of the Challenge was to generate a progress in aircraft designing, it was not only pilots' competition, but technical trials also included a construction evaluation, to build more advanced and reliable touring planes.[1] All planes flew with two-men crews, pilot and passenger or mechanic (apart from the Swiss Charles Kolp, who took two passengers, including one woman, into his Klemm VL.25.

Most of the aircraft in the contest were popular sport planes of the late 1920s, that took part in the previous contest as well, like de Havilland Gipsy Moth DH-60G, which was the main aircraft of the British and Spanish teams. These aircraft had mostly open cabs, and were built in mostly low-wing (29) or high-wing (17) layout, only 13 were biplanes (and 1 mid-wing).[4] Only five were of all-metal construction, most were all-wooden.[5] On contrary to a previous contest, there appeared also some special aircraft, better suited to meet the Challenge demands. First of all, they were German BFW M.23c and Klemm L 25E, being new variants of successful machines of 1929 – wooden low-wing monoplanes with closed canopy, belonging to lighter category, yet fitted with powerful Argus engines, having better chance in technical trials. All aircraft in the contest had fixed conventional landing gear and had no wing mechanization (slats or flaps) yet.[4] Aircraft participating were BFW M.23c (10), BFW M.23b (1), Klemm L.25 (4), Klemm L.25E (3), Klemm L 26 (2), Klemm VL 25 (1), Junkers A50 (3), Arado L II (4), Albatros L 100 (1), Albatros L 101 (1), Darmstadt D-18 (1), de Havilland DH.60G Gipsy Moth (6), Avro Avian (1), Spartan Arrow (1), Monocoupe 110 (1),[6] RWD-2 (3), RWD-4 (3), PZL.5 (2), PWS-50 (1), PWS-51 (1), PWS-52 (1), PWS-8 (1), Caudron C.193 (3), Caudron C.232 (1), Peyret-Mauboussin PM XI (1), Saint Hubert G1 (1), Breda Ba.15S (1), CASA C-1 The contest in 1930 was the only Challenge, in which a rally was the opening phase.[1] It was a 7560 km circuit over Europe, with compulsory stops at: Berlin – Braunschweig – Frankfurt – Reims – Saint-Inglevert – Bristol – London – Saint-Inglevert – Paris – Poitiers – Pau – Zaragoza – Madrid – Seville – Zaragoza – Barcelona – Nimes – Lyon – Lausanne – Bern – Munich – Vienna – Prague – Breslau (Wrocław) – Poznań – Warsaw – Königsberg (Kaliningrad) – Danzig (Gdańsk) – Berlin. Distances ranged from 77.5 km (Lausanne – Bern) to 410 km (Danzig – Berlin).[10] In spite of attempts of many pilots at being the first man home, it was not a race, but rather a reliability test. A regularity of flights was the most important factor, the second was a cruise speed (minimal cruise speed had to be 80 km/h for Class I aircraft or 60 km/h for lighter Class II aircraft. Cruise speeds above 175/155 km/h respectively did not give extra points).[10] The average speed was judged on flying time, so a competitor had to have his log book signed as soon after landing as possible.[8] A competitor was given 75 points for regularity, which were mulcted for spending nights off the control airfield or not covering any stage in a day. One night outside the control or arrival after the official closing time (8 p.m.) costed 15 points, two nights – 45 points, and three failures to reach the control caused a disqualification. Also, for failing to fly any stage in a day, a competitor would lose 10 points, and for the second time – another 20 points.[3] The original time limit for the return to Berlin was 4 p.m. on July 31, but it got extended later for some crews, due to bad weather in Pau.[8] Apart from 75 points for regularity, up to 195 points could be gained for a high cruise speed.[10] Comparing with 1929 competition, the rally could bring only 54% of maximum number of points (in 1929 – 72%), what meant more stress on technical trials
