Labor Day Week fly-in, it occurred to me that WWI fighters could have
solved their gun aim/synchronization problems easily by adopting a
pusher prop configuration.

In addition to the Vickers Gunbus already mentioned are the Airco DH.1 and
DH.2 and the Royal Aircraft Factory F.E.2 but I'm sure there were more.
