If you want to get a book on WW1 aviation then this is good. Has colour plates of aircraft and is a good all-round title. 
 

Hell's Angels - A Howard Hughes Production (1930)

 From the wiki. Noticed it is coming out on 4K Blu-ray. 

Hell's Angels is a 1930 American pre-Code independent epic war film directed and produced by Howard Hughes and director of dialogue James Whale. Written by Harry Behn and Howard Estabrook and starring Ben Lyon, James Hall and Jean Harlow, it was released through United Artists. It follows two dissimilar brothers, both members of the British Royal Flying Corps during the First World War.

The film was originally shot as a silent film. The Jazz Singer, which ushered in the sound era, premiered several weeks before the start of principal photography for Hell's Angels and left the public clamoring for talking pictures. A year and a half later, Hughes decided to convert his film to sound. The original female lead, Norwegian-American Greta Nissen, had to be replaced due to her accent. Jean Harlow became a major star as her successor. The production took three years (1927–1930) and Hughes spared no expense, so that despite being one of the highest-grossing films of the early sound era, it did not recoup its exorbitant $2.8 million cost.^[4]

The Battle of Gravelotte (or Battle of Gravelotte–St. Privat) on 18 August 1870 was the largest battle of the Franco-Prussian War. Named after Gravelotte, a village in Lorraine, it was fought about 6 miles (9.7 km) west of Metz, where on the previous day, having intercepted the French army's retreat to the west at the Battle of Mars-la-Tour, the Prussians were now closing in to complete the destruction of the French forces.

The Battle of Mars-la-Tour (also known as the Battle of Vionville or Battle of Rezonville) was fought on 16 August 1870, during the Franco-Prussian War, near the village of Mars-La-Tour in northeast France. One Prussian corps, reinforced by two more later in the day, encountered the entire French Army of the Rhine in a meeting engagement and, following the course of battle, the Army of the Rhine retreated toward the fortress of Metz.
