Congo Republic – BAC-111 Aircraft – 1000 Francs – 2004 – Proof Silver Crown – Color – The British Aircraft Corporation One-Eleven, also known as the BAC-111, was a British short-range jet airliner of the 1960s and 1970s. Conceived by Hunting Aircraft, it was developed and produced by the British Aircraft Corporation when Hunting merged into BAC along with other British aircraft makers in 1960. The BAC-111 was designed to replace the Vickers Viscount. It was the second short-haul jet airliner to enter service. Due to its later service entry, the BAC-111 took advantage of more efficient engines and airline experience of jets. This made it popular, with over half of the sales at its launch being in the largest and most lucrative market, the United States. It was one of the most successful British airliner designs, and served until its widespread retirement in the 1990s due to noise restrictions.

Congo Republic – Junkers JU-52 Aircraft – 100 Francs – 1995 – Uncirculated Crown – Color – Nicknamed “Tante Ju” (Auntie Ju) and “Iron Annie” by Axis and Allied troops, the Junkers Ju-52 was the most famous German transport of the war. The Ju-52 was built of corrugated metal skin and paid little attention to beauty, features of a typical Junkers design. Parts and pieces stuck out of the airframe, and the corrugated skin, though much stronger than fabric and metal tubes, created stronger air resistance. In April 1931, the originally single-engine Ju-52 prototype was fitted with three engines. Performance improved tremendously and production of the new model immediately began. The Ju-52 served as an airliner for many nations. Finland, Spain, Sweden and Germany were just a few. It served as a mail carrier in China, and, fitted with floats, hauled lumber in remote places in Canada. Its most common work, however, was done with the German Lufthansa. Equipped with luxuries like a typewriter and oxygen masks, the Ju-52 could fly from Berlin to Rome in eight hours over the Alps, an impressive feat for contemporary aircraft, let alone an airliner. The military potential of the Ju-52 was not overlooked by the Luftwaffe. It entered service as a troop transport and bomber. In the Spanish Civil War, the Ju-52 ferried some 10’000 Moorish troops from Morocco to Spain, and bombed Madrid while, quite embarrassingly, some Lufthansa Ju-52s were in the airport serving as airliners. Later in World War II, the Ju-52 served in every theater in which Germany participated. It dropped paratroopers in the Netherlands, Crete and later the Ardennes. It carried supplies to beleaguered troops in North Africa, Stalingrad and the Baltic states. The Ju-52 was slow and very lightly armed against fighters. As a result, it suffered horrible losses in almost all actions, especially over Crete, the Mediterranean and Stalingrad. Many types of replacement were built, but none was as popular or reliable as good old Auntie Ju. Right until the end of the war the Ju-52 was still soldiering on to help stave off defeat. The last Ju-52s went out of service with the Swiss Air Force in the late 1980s
