HC Deb 12 March 1917 vol 91 c743W
Mr. BILLING

asked how many aeroplanes and seaplanes have been deleted from the Royal Naval Air Service and how many aeroplanes have been deleted from the Royal Flying Corps, respectively, within the last twelve months?

Major BAIRD

I regret that I cannot supply these figures, the publication of which might assist the enemy in calculating the actual strength of our air services in the field.
