We reached the first altitude with ease. The sky was covered with huge clouds, the air icy. When we rose through the bank of clouds into the glorious sunshine we had a beautiful experience. We suddenly saw a radiantly shining Zeppelin, which was likewise attempting a flight at high altitude. What a marvellous meeting—3000 metres up in the air! Far away from toiling humanity, high up above daily strife and pain, the two birds of the air—striking evidence of Germany’s strength and enterprise—saluted each other. We flew several times round our big brother, and waved our hand to him in friendly greeting. But after that we had to apply ourselves seriously to our task and work strenuously in order to attain our objective. After an hour we had gained an altitude of 4800 metres, after that 4900, my barograph soon showed 5000, and the propeller hummed its monotonous melody. Linnekogel veered quietly and methodically. The thermometer rose to 37 degrees Celsius; but we paid no attention to the cold. Only the air became rarefied. A slight sensation of drowsiness came over me, and my lungs only functioned in quick, short gasps. Every movement became irksome. Even to turn round towards the pilot who sat behind me seemed a huge effort. The sky had cleared and looked glorious. The cloud-banks had vanished, and we could distinguish our capital lying far below us in the blue distance like a black spot, on which, however, we could still note the straight line of the Charlottenburger Chaussee, culminating in the thoroughfare Unter den Linden. I was so carried away by this view that for some time I paid no attention to either watch or barograph. But I suddenly realized my omission with a start. Twenty minutes had passed since I had registered my barograph at 5000 metres, and by now we should have beaten our record. But I was terribly disappointed to see that the needle still indicated 5000. At the same time, Linnekogel began signalling to me to look for the aerodrome, pointing downwards with his hand. That was too bad. I turned away disgustedly, and, when Linnekogel failed to notice it, I kicked his shin with none too much gentleness. I likewise spread out my five fingers and pointed upwards. This meant: Higher, higher! We have only got to 5000 metres! Linnekogel only laughed. He gripped my hand, shook it hard, and opened and shut the five fingers of his right hand twice. I really thought he had gone dotty. And what confirmed me in my opinion was that Linnekogel throttled the engine. We were just above Potsdam, and glided towards the aerodrome of Johannisthal. It was now my job to find the landing-place. And sixteen minutes later we stood safe and sound before the Rumpler-hangars, joyfully acclaimed by crowds of spectators. We had done it! The world’s record was broken with 5500 metres.
