It was asked previously how Hitler's plane managed to fly undetected from Prague on 27 April 1945? The same way it did on 5/6 April 1945 when rather embarassingly it crashed on landing at Barcelona. A Fw200 flew in spare parts to repair the undercarriage so the aircraft could repeat the trip on 27 April. Not quite undetected since the crash on 6 April did not go unnoticed. Someone remarked this is all very boy's own stuff, but in fact WW2 was full of Boy's own stuff and all who participate in this and other WW2 forums are grown men with a boyish fascination for WW2... There is no secret in that. Also WW2 itself is full of examples of boyish escapades like for example HMS Cambletown ramming the gates at St Nazaire, Skorzeny rescuing Mussolini by glider landing, capture of the Pegasus Bridge at Normandy are all examples that in War forces on either side do improbable acts to gain the advantage. At Matsuwa Island in the Kuril Islands is a volcanic cone with a flat area on one side of the island. Here the Japanese built an air base with one 2000m runway and another 1500m runway, both of which they plumbed underground with geothermal steam to keep it snow free year round and on that airfield even today you can still find German WW2 era 44 gallon drums among the debris of Japanese infantry helmets. This particular island just a pimple in the Pacific yet none the less had an impressive system of bunkers and fortifications with an 8,000 strong garrison, radar and it's own fighter squadron plus 60 tanks...why so much effort? What were the Germans doing at Matsuwa? Also regards a German General sent to Cordoba in Argentina to supervise former Graf Spee crew to build an airstrip, there is nothing unbelievable in that either. Germany used the airstrip at Vila Cisneros, on the Spanish Sahara coast, as a refueling stop both before the war and during the war for flights to South America.
