by Tresckow's friend General Stieff. It concealed a bomb, disguised in a box for two bottles of Cointreau. Von Tresckow's aide, Lieutenant Fabian von Schlabrendorff, set the fuse and handed over the parcel to Brandt who boarded the same plane as Hitler. Hitler's Focke-Wulf Fw 200 Condor was expected to explode about 30 minutes later near Minsk, close enough to the front to be attributed to Soviet fighters. Olbricht was to use the resulting crisis to mobilise his Reserve Army network to seize power in Berlin, Vienna, Munich and in the German Wehrkreis centres. It was an ambitious but credible plan, and might have worked if Hitler had indeed been killed, although persuading Army units to fight and overcome what could certainly have been fierce resistance from the SS could have been a major obstacle. However, as with Elser's bomb in 1939 and all other attempts, luck favoured Hitler again, which was attributed to "Vorsehung" (providence). The British-made chemical pencil detonator on the bomb had been tested many times and was considered reliable. It went off, but the bomb did not. The percussion cap apparently became too cold as the parcel was carried in the unheated cargo hold. Displaying great sangfroid, Schlabrendorff took the next plane to retrieve the package from Colonel Brandt before the content was discovered. The blocks of plastic explosives were later used by Gersdorff and Stauffenberg. Suicide bombing attempts A second attempt was made a few days later on 21 March 1943, when Hitler visited an exhibition of captured Soviet weaponry in Berlin's Zeughaus. One of Tresckow's friends, Colonel Rudolf Christoph Freiherr von Gersdorff, was scheduled to explain some exhibits, and volunteered to carry out a suicide bombing using the same bomb that had failed to go off on the plane, concealed on his person. However, the only new chemical fuse he could obtain was a ten-minute one. Hitler again left prematurely after hurrying through the exhibition much quicker than the scheduled 30 minutes. Gersdorff had to dash to a bathroom to defuse the bomb to save his life, and more importantly, prevent any suspicion. This second failure temporarily demoralised the plotters at Army Group Centre. Gersdorff reported about the attempt after the war; the footage is often seen on German TV documentaries ("Die Nacht des Widerstands" etc.), including a photo showing Gersdorff and Hitler.
