This talk is a sequel to Mr. Filson Young 's entertaining and instructive series ' Growing Wings ', in which he told listeners of his experiences while learning to fly, but, unlike most sequels, it goes back nineteen years, and is to describe the even greater adventure of learning to fly in war-time. Aircraft in 1915 were often very rickety affairs, and the temper of war-time instructors added to the difficulties. Mr. Insall's experiences offer an amusing contrast to conditions today.
