It must also be remembered that most of the days on which machines were 

 unserviceable were days when weather was unfit for flying, so that necessary 

 engine changes were cared for with little interruption to service. Of 821 patrols 

 requisitioned 97.81 per cent, were successfully carried out, as compared with 

 97.3 per cent, of only 555 requisitions in 1925.
