HC Deb 30 November 1926 vol 200 cc991-2
14. Mr. THURTLE

asked the Secretary of State for War if he can make a statement as to the object of the recent action of his Department in sending a company of soldiers into the London postal tube and keeping them there for a number of hours?

Sir L. WORTHINGTON-EVANS

The experiment was designed to furnish data regarding the ventilation required under certain conditions in underground shelters, such as dug-outs.

Mr. THURTLE

Was it undertaken with a view to finding out information for the provision of shelter for the civilian population in the event of air-raids?

Sir L. WORTHINGTON-EVANS

Not exclusively. Both the military and the civil population will be subject to somewhat the same conditions. The experiments were intended to provide some information with respect to ventilation.
