Adding to the play's drama was another event of 1916. On 1 October, a German Zeppelin, the L-31, was shot down over north London. The day after, Shaw went to see the downed airship. Shaw had the honesty to admit that the whole incident had fascinated him. To the Webbs he confessed:
What is hardly credible, but true, is that the sound of the Zepp's engines was so fine, and its voyage through the stars so enchanting, that I positively caught myself hoping next night that there would be another raid . I grieve to add that after seeing the Zepp fall like a burning newspaper, with its human contents roasting for some minutes (it was frightfully slow) 1 went to bed and was comfortably asleep in ten minutes.
