It has been my endeavour throughout these tales not only to chronicle some of the wonderful work done in the air, but also to show the connection between it and that of the Armies on the ground, the assistance rendered in so many ways by the air arm, and its value in a battle and in a campaign. I hope that my stories may show something of the skill and daring of the air men and--what is less well known to the public--how much they are doing to save the lives and cut down the casualties of the men on the ground, and to help our arms to victory. Already I have been rebuked for exaggerating and making my characters perform impossible feats, so I may forewarn the reader that I have written nothing here for which I cannot find an actual parallel--and in some cases even more wonderful--fact. Practically every incident I have pieced into my tales has, to my own knowledge, occurred, and I have left untold many which for sheer sensationalism would beat these hollow. There are many in the Air Force who will recognise incidents and feats, but will not recognise the characters I have attached to them, because--mainly at the urgent wish of the men themselves--I have used entirely fictitious characters and names throughout. Because most of the writing was done while the R.N.A.S. and R.F.C. were still in existence I have left this as written. I ask the indulgence of critical readers amongst the air men to any technical errors they may discover (knowing how keenly they will look for them). I make no pretence to being a flying man myself, but because I have done flying enough--or rather have been flown, since I am not a pilot--to know and appreciate some of the dangers and risks and sensations of the work, and have lived for over a year in the Squadrons at the Front, I cherish the hope that I have absorbed enough of the nature and atmosphere of the work to present a true picture of the life. I shall be very well content if I have been able to do this, and, in any slightest degree, make plain how vital to success a strong Air Force is. I have had experience enough of the line, and have gained enough knowledge of the air, to be tremendously impressed with the belief, which I have tried in this book to pass on and spread, that every squadron added, every man trained, every single machine put in the air, helps in its own measure to bring us to final victory, more quickly, and at a less cost in the long and heavy "butcher's bill" of the war.
