Hugh Trenchard, 1st Viscount Trenchard

"We want the mathematical genius - there is work for him. We want the literary genius - there is work for him, especially in my office. We want the scientific brain - there is more than enough work for him. We want the man of brains and we want the man of common sense and little brain. We want the man of initiative and the man of action, the methodical man and even the crank. We open our ranks widely to all."

"The development of air power in its broadest sense, and including the development of all means of combating missiles that travel through the air, whether fired or dropped, is the first essential to our survival in war."

"The Great War only produced two things of importance, barbed wire and Trenchard."
