HC Deb 06 April 1927 vol 204 c2066
74. Viscount SANDON

asked the Secretary of State for Air if any observation balloons are at present in commission; if so, how many; and, if not, how personnel are kept in training in this branch?

Sir S. HOARE.

Two balloons are at present kept in commission for training purposes. As I informed my Noble Friend on the 30th March, it would be undesirable to give details as to the scale on which we are prepared to mobilise this branch of the Service in the event of war.
