Great photography, mistaken premise...

Rating: 4/10 (18 March 2020)

Loved the photography, and the equipment and uniforms were mostly correct in their detail.
However, the plot is explained by Colin Firth, that the British reconnaisance aeroplanes have produced 'aerials', showing an unprecedented build-up of German forces, and that if the Devons proceed in their attack, they will walk into a trap, therefore, the two designated soldiers must deliver the message before it's too late.
I couldn't help think, if they have the evidence in the form of aerial photographs, and they plainly already know the location of their own attacking forced, why on earth can't they drop messages to the Devons, via the same Royal Flying Corps aeroplanes, directly to the Devons? That thought was immediately reinforced in the scene where British aircraft shot down the German in front of our two central messengers.
I saw my point is listed as a frequently asked question. The response from someone was that aircraft were a relatively new thing at the time, and quite sparse!
Oh well...
