Book I just learned of "Adventures of a Motorcycle Despatch Rider During the First World War"

 I can see that these seem the same by topic, but have different authors, and I don't have an answer for that, other than to say I think they are likely to either be the same, or similar.

Looks interesting, I'll get a copy one day when they come down in price

"Airplanes are like women, they are all beautiful, but only the ones with guns are interesting" is the tagline for the tumblr Remove Before Flight. I like that

the vehicles in the movie War Horse

1911 Vauxhall C type

 the above bike is the only vehicle that has recognizeable nameplate or logo, it's a Premiere. It is a 1913 Premiere 500cc.  The above is a British character, the below are German

the Internet Car Movie database says the above are 1924 Triumph SD

Ever notice that movies seldom show the variety of vehicle relative to the fuel type? No alcohol, steam, or electric, and I doubt I covered the handful of other fuels... they just can't afford the cars or trucks that are that unusual I suppose. Anything that isn't gasoline probably isn't very easy to get ahold of

Just a gust of wind

This misfortunate pilot landed his vintage tri-plane on its nose. The man had been flying the famous Fokker Dreidecker aircraft at the Flying Legends airshow at the Imperial War Museum in Duxford, Cambsridgeshire. But when he landed the WW1 fighter aircraft a sudden gust of wind blew it on its nose. No one was hurt in the incident.
