From Sydney with Love...

[The Rock Doctor]

So that's our first clue:  no Swiss capable of reporting back.

May 2nd, Sydney Times

Score one for the Royal Australian Zeppelin Air Service! Let those who dare fight the Swiss know that their capital is no longer inmune! Yesterday zeppelins from Sydney struck the German capital of New Brandenburg, with a new and powerful weapon, leveling all military facilities in the capital, and badly damaging the powerful battlecruiser Geniseau. While the RAZAS has made no comment on the powerful new weapons used, one of the crewmembers hinted at something he called a 'Hydrogen Bomb'...

Actualy, a hydrogen Zeppelin doesn't explode....  It burns fiercely tough, especialy painted in a halfway rocketfuel.

There are ways to make it explode, but that would need some fancy technologies, maybe in the 1910 realm of possibility. But that is very very doubtfull. 
On the other hand, a 1 ton bombload will make a nice cloud in its own respect.

[Ithekro]

Makes for decent propaganda, if there are any physicist that know anything about the atom to guess what a "hydrogen bomb" could do rather than just a buring bag of hydrogen.

[maddox]

in 1909? Not even the power of fission is imaginable.
Even it's the time of great discoveries. Marie Curie, workign herself to death , even in the Nverse variation.

[Sachmle]

So not so much an explosion, at least from the airship. But... if it caught fire and crashed into say... an ordinance storage facility then maybe a nice boom.

(Considering the airship seems to have run into a light house I doubt the damages are all that much)

Just two more hours, tought Lutjens. By four o'clock his relief would arrive and he would be able to go home. Wait what was that? There caught in the beam of the Brandenburg lighthouse was the massive shape of a zeppelin. That was the last thing Lutjens saw, as a fireball brighter than the sun erupted in front of his eyes. Within a few seconds the windows of the deckhouse shattered explosively and a giant hand slammed Lutjens into the wall, turning day into night...

Well let's see...take a hydrogen zeppelin, punch it full of holes to get a nice H2+O2 mixture, load it with 5 tons of cordite, and install extra gasoline (not diesel) fuel tanks (which are then modified with bullet holes). You should get a very decent explosion out of it.

Strongly doubt ANYTHING remains of that poor lighthouse. The explosion should also be strong enough to break windows all over Brandenburg, but that's about all the damages caused to the city.

Hmmm.. Thought I had seen something interesting here awhile ago...

Borys your sneaky....  ;D
