Some military critics, when such facts as these are adduced, raise the point that such "air-worthiness" as this is not sufficient. The complications of war are already so great, they declare, that a Commander-in-Chief is not justified in increasing his responsibilities by saddling himself with a squadron of aeroplanes, when the machines will be inoperative should a high wind spring up. "Enthusiasts do not seem to realise this point," a military critic has observed, in regard to the general question of aeroplane reliability. "A commander of troops would, almost, be more hampered than helped by an air service, were it only possible to use it one day, and then not the next, and so on. He would rely upon it, you see, and then it would fail him just at some critical moment. I know it may be said, in answer to this, that even if only occasional use can be made of aeroplanes, it is worth while to equip an army with them, because, if they succeed in their object once in six times, they may alter the whole course of a battle. But it must be remembered that a very considerable organisation has to be built up, if an aeroplane service is to be of any real use. The already huge impedimenta of an army has to be added to; and this, alone, is a very serious point. On account of the unreliability of the air service, also, cavalry scouts, and other scouting agencies, have to be employed, just as usual. The position is, really, a somewhat unsatisfactory one. For days on end, if the weather is bad, the aeroplanes may be inoperative." This view is, of course, an unduly pessimistic one. Having regard to the capabilities of present-type aeroplanes, the occasions upon which war machines would be windbound would be very rare. It is reliably estimated, in fact, that aeroplane scouts would be able to render good service on 80 per cent, of the days of the year. It might happen that a boisterous wind, rising in the morning, would prevent the air-scouts from working at midday, or during the afternoon. But, even during a generally unfavourable spell of weather, a shrewd Commander of aeroplanes should be able to snatch an hour’s lull in the wind, probably in the early morning or evening, and get his machines to work. Either a morning or evening calm, during a period of gusty winds, is generally experienced; and, in any such lull, so rapid is their work, the aeroplanes should be able to acquire what information is necessary, and be back again at Headquarters, before any hazardous rising of the wind takes place. In this way, it should be possible to manipulate the service, even with existing machines, so as to make it of practical value, upon almost every day of a campaign; and the fact that one hour’s work would probably be sufficient for a reconnoitring flight, is the important factor of the situation to be remembered.
