This is not from the "Blitz". The photo above is taken after the October 14th, 1915 raid on London. Yes, London was bombed in World War One. It was bombed by Zeppelins. This one killed dozens of civilians. Interestingly enough, the Germans stopped the Zeppelin bombing. They would not bomb London again until they built their bombers and deployed them much later in the war. Zeppelins were not just used for random bombings but were for recon and troop formation spotting. Opponents would send fighter planes to then take them out, forcing zeppelin defender wings on the German side.
Zeppelins were not the blimps we see over sports arenas today. Zeppelins were much larger (double the length). It is not just nostalgia talking, but I'd love to see the return of zeppelins. For all the SWPL love of rail travel, why not travel in something of comparable speed (80 mph) but far more luxury as you are in the skies. The slow speed also removes terrorist "planes as missiles" risk. When the US breaks up, can one regional bloc that forms create a Zeppelin network? Midwestopia or Dixie, can you do this? I'll take this over a plane any day.
