View Zeppelins over London in a larger map
Last year, Londonist gave us a very nifty map of London's V2 impact sites. Now they've come up with an equivalent for Zeppelin raids. Each of the sunbursts represents a bombfall. Clicking on them brings up a popup with information about the site and casualties (but, annoyingly, not the date). Note, however, that only a 'small selection' of the sites are plotted, however, which makes it hard to draw conclusions from the patterns: I could be wrong but I don't think the cluster in central London is representative. But perhaps more interesting are the tracks of the Zeppelin raiders (to get the key for which raid was when, click on the 'larger map' link). Again, these need to be treated with some caution, as they would only be reconstructions based on logbooks, bombfalls and sightings, but they do suggest that if the raiders could get reasonably close to London they could usually work out where to go. You can see the tracks deviating towards the urban areas, or turning back after the bombing run. London did have a blackout during the First World War (when its fighters couldn't touch the Zeppelins, the government claimed that the best defence against them was 'darkness and composure') but it wasn't as complete as during the Second. And of course the Thames on a clear and moonlit night couldn't be blacked-out at all.
Also, note the link in comments to a sequence of photos showing a Zeppelin being shot down. I hate to say it but I think these are fake ...
