From the ‘Nottingham Evening Post,’ 1st November 1917.


In the early hours of 20th October 1917, disorientated, suffering from airsickness, with only two engines working and attacked by Nieuports of Escadrille N.152, Zeppelin L49 came down in France.

It was examined in great detail by the British and French and an account of an inspection by an American “air expert” was published on 1st November 1917.

SECRETS OF THE L49.

FINDINGS OF AN AMERICAN EXPERT.

FROZEN WATER BALLAST.

An air expert of the Chicago Daily News, who visited the wrecked Zeppelin at Bourbonne-les-Bains, has communicated the following account of his impressions to the Press Association’s correspondent.

“Having just visited Zeppelin L49, which fell five kilometres from here, I have been struck by a number of facts. In the tanks there was still a large amount of petrol. The alcoholised water used for fluid ballast was frozen in the reservoirs, and in the 19 balloons of goldbeaters’ skin there was a great lack of gas. The only conclusion to be drawn from these facts was that the Zeppelin’s descent was caused by want of gas, and the impossibility of dropping ballast owing to the freezing of the water.

“Two meteorological authorities have informed me that the Zeppelin’s commander was, in all probability, deceived by the heavy wind like a mistral, which was more violent at the higher than at the lower altitudes. The highest altitude shown by the instruments was 7,000 metres, and rising to this height no doubt resulted in loss of hydrogen, and caused the liquid ballast to freeze. After descending to a lower altitude the commander was unable to reduce his ballast but went on in the hope of reaching Germany. French fighting machines, however, forced him to land. Hoping to set his machine on fire, the commander fired his pistol at the Zeppelin until stopped by a French sentinel. Fortunately he did not succeed. His only remark was ‘As you please, but I thought I had the right to destroy my machine when I surrendered.’


“COMFORTLESS CONVEYANCE.

“I went all over the captured airship from the turret platform to the cars. In the wireless telegraphy compartment I found some dry biscuits marked ‘Hanover,’ but was afraid to taste them for fear of poison.

“After all I had heard of Zeppelin comfort, I was surprised not to find much. On the contrary, I should not care to pass a night in one, even for the pleasure of bombing Berlin. The means of communication in the interior of the envelope consisted of an aluminium bridge 4½ inches wide of very fragile construction made of small pieces of aluminium and thin wood, with wire here and there to assist the passenger in keeping his balance. The sides of the bridge were merely waterproofed cloth – nothing else between the passenger and the ground beneath, but all, perhaps, that was necessary. But, still, I confess to being somewhat surprised at the makeshift appearance of the construction and workmanship, of which any English or French workman would have been ashamed.

“One notable exception, however, was the wireless room and installation, which closely resembled that of a transatlantic line of the latest type. According to a French expert who was sent to examine the apparatus, it included several new features of some importance. He assured me that in spite of the operator’s attempt to destroy the machinery before abandoning the ship, it would be possible to reconstruct the apparatus completely,

“Forward of the wireless room, the roomy bridge on the control station was furnished with a fibre mat, and with thick glass wind-shields on all sides. On the right and in the centre were two wheels for the elevating and directing rudders respectively, like those on a small motor yacht. A chart table stood on the right. Square stools, with rounded corners, made of thin wood, were used here elsewhere. They were so lightly made that when a French officer stood on one in order to reach the envelope it collapsed.

“IN THE ENGINE-ROOM.

“Aft of the wireless room stands the engine-room, where the largest of the five motors actuates the direct drive propeller. This is reached by a ladder which leads to a narrow path, 500 or 600 feet long, within the envelope. On the engine-room floor there was a folded parachute, which looked as though the engineer wore it attached to his shoulders until the moment when the commander decided to surrender.




“From this main motor-room, where the engine is twice the power of the others, I walked inside the envelope along a frail, narrow path of little sticks mounted on aluminium to a point where two diverging paths led to the nacelles.


“On the way I passed a tube of balloon cloth, enclosing an extremely light aluminium ladder, with rungs as far apart as possible, and leading to this was a wooden ladder reminiscent of those used for toy dog performances, but probably much less strong. I climbed uncertainly some 40 rungs to the top of the envelope, where was a small gun platform for two men and machine guns. I noticed here that the top of the envelope was almost white, shading gradually into black towards the lowest part.

“The aft nacelles, one on each side, were reached by ladders about eight feet long leading down from the interior of the envelope. Each of these contain two motors driving a single propeller – two motors being employed so that only one may be used on each side if it is desired to economise fuel.

“Inside the envelope are 19 balloons of goldbeaters’ skin, with smaller balloons built into them for the purpose of taking any overflow of gas, or if required they can be inflated by means of valves which are controlled from the navigation bridge forward.

“The envelope also contains water tanks of canvas, with a capacity of two hundred litres each, evenly distributed. This water ballast can also be controlled from the bridge. There are besides 16 petrol tanks of very solid construction, so arranged that any motor can be fed from any one tank. The rest of the contents include some spare parts, hammocks for the crew, which were probably not much used this last journey, and the aluminium framework that gives the envelope its shape.”
