The German Zeppelin L2 was the second Zeppelin airship to be bought by the Imperial German Navy. It caught fire and crashed with the loss of all aboard on October 17, 1913 before it even entered service.
The Zepplin was first flown on September 6th and following a number of trial flights it was flown to Johannisthal in northeastern Germany on September 20th for an acceptance trial by the Navy.
This trial flight, the craft's tenth, was to be an altitude trial and was scheduled on October 17th. On the morning of the flight things started badly. Takeoff was delayed because one of the engines wouldn't start.
During the two hours it took to repair the engine the airship was sitting in the sun and the heated hydrogen expanded. As a result, on takeoff the airship ascended rapidly to about 650 feet and that's when observers saw flames leaping out of the forward engine car.
The flames caused some of the gasbags to explode and the airship began plummeting to the ground. Halfway down there was a second explosion and as the wreckage hit the ground there were more explosions as the fuel tanks ignited.
Medical personnel were there immediately and shortly thereafter several ambulances arrived. Two crew members were found alive lying outside the debris and severely wounded lieutenant was freed from the wreckage. Of the three survivors one died at the site, the second died during transport to the hospital and the third died in the hospital. The remaining 25 crew members were killed on impact.
Among the 28 crew members who died in the crash was one of the strongest members of the Berlin Chess Club (Berlin Scachgegellschaft), Captain Max Behnisch who was in command of the airship.
It was determined that the accident had been caused by the rapid ascent leading to venting of hydrogen through the relief valves, which in Zeppelins of the period were placed at the bottom of the bags; there were no vents to convey any hydrogen let off to the top of the ship. As a result, some of the vented gas was then sucked into the forward engine car where it was ignited, the fire then spreading to the gasbags.
Korvettenkapitaen Max Behnisch (1873-1913) had been in the German Navy for 15 years originally serving as a corvette captain; a corvette is the smallest class of vessel considered to be a proper warship. He had commanded the gunboat Panther when, in 1911, he was appointed to the Reichsmarineamt where he was head of the aviation department.
Behnisch was the son of the director of the Gorlitz mechanical engineering and iron foundry corporation. His family (mother and sister) received the news of his death at 1:00pm by telegram from Berlin.
Although Behnsich was not a Master, he was a highly esteemed as an amateur player as well as for his personal qualities. He enjoyed the distinction of having been the only player to have defeated Emanuel Lasker in a simultaneous exhibition at the club in 1912. Lasker himself spoke very highly of the brilliant effort by Behnisch,
It was very audacious of Behnisch to play the Scandinavian, but it paid off because he obtained good development and fine attacking possibilities. Then, a temporary sacrifice of a N enabled him to make progress and Lasker found it necessary to give up the exchange.
In 1912, at the annual congress of the German Chess Association Behnisch participated in one of the minor tournaments at the Breslau International Congress. After the conclusion of the events the Breslau officials arranged an extra quadrangular tournament with the order of finish being 1) Hugo Suechting 2) Walther von Holzhausen 3) Behnisch and 4) Dr. Carl Hartlaub.
Unfortunately, I was unable to discover any of Behnisch's games except for his win over Lasker.

{Scandinavian Defense} 1. e4 d5 {This used to be known as the Center Counter
