Erbslöh
The Erbslöh was an airship named after the German aviation pioneer Oskar Erbslöh from Wuppertal that was operational in the years 1909/10. In July 1910 the Erbslöh crashed near Leverkusen, killing all five people on board.
History
The Erbslöh was a blimp with a 27-metre (89 ft) long cabin made from ash wood. The cruising height was regulated by pumping water back and forth between two tanks in the bow and aft section of the ship so that a declination was caused.
The first test flight took place on 20 August 1909. After the airship had been moved out of its hangar, the maneouvrability was tested for about one hour at a height of 100 metres (330 ft) on the Leichlingen airship grounds. The official maiden flight was conducted on 1 December 1909 during which the airship successfully flew across Leichlingen and neighbouring towns.
On 12 December supporters of the Rheinisch-Westfälische Motorluftschiff-Gesellschaft [Rhine-Westphalian Motor Airship Society] participated in a flight. However, a transmission fault forced the Erbslöh to land at Reusrath. When the faulty parts had been repaired, the Erbslöh flew on toward Mönchengladbach on the next day. The intermediate stop over there was terminated by a storm which tore the envelope off the cabin. Thereafter an extensive repair was necessary.
The end
On 13 July 1910, a partly cloudy day, the airship Erbslöh crashed near Pattscheid (today a quarter of Leverkusen). The cause that was accepted by the subsequent investigation committee was: a sudden exposure of the envelope to the sun after the ship had been flying under cloud cover and cool morning fog. When the lifting gas was thus heated, it began to expand. The relief valves could not divert the developing excess pressure inside the envelope fast enough, so that the valves were overwhelmed. This allowed hydrogen lifting gas to come into contact with sparks from the propulsion system, causing the gas to explode. The burning ship fell down out of the air.
Witnesses on the ground only heard a bang, the ship was not visible in the morning fog. The Erbslöh crashed close to Neuenkamp on a field. The front part of the cabin was destroyed with the torn envelope lying across it. The crew was found dead among the debris. Actually the ship should have flown over Leichlingen for only half an hour.
In addition to Oskar Erbslöh, crash fatalities included Max von Toelle, Rudolf Kranz, Hans Leo Höpp, and mechanic Joseph Spicks. A monument was erected at the "Oskar-Erbslöh-Straße" [Oskar Erbslöh Road] of Leichlingen in memory of them.
