HC Deb 21 December 1927 vol 212 c428W
Colonel DAY

asked the Secretary of State for Air how many aeroplanes known as the Isacco Heliogyre have been acquired or are being built; and what is the approximate cost?


The Air Ministry has purchased a plan of the machine referred to and the right to build one aircraft of this type, but no such aircraft has been acquired and it will be some time before sufficient technical preparation can be made, conjunction with the inventor, for building a machine; the second part of the question does not arise.
