§ The UNDER-SECRETARY of STATE for AIR (Sir Philip Sassoon)
In answer to the first part of the question, the airship will be inflated with hydrogen. As regards the second part, the estimated cost of 5,000,000 cubic feet of hydrogen is £2,500; the cost of helium would be very much greater, but no exact data are available.
§ Sir P. SASSOON
The erection of the hull is not yet commenced, but the construction of component parts is in hand.
