HC Deb 14 May 1947 vol 437 cc166-7W
88. Mr. Edward Davies

asked the Minister of Supply if he will make a statement on the recent experiments made with telescopic airscrews to achieve greater safety in aviation.

Mr. Woodburn

This device is at present in the development stage and so far tests of rotors intended for fitting to parachutists have been restricted to ground runs. Facilities for testing from aircraft are now being made available to the inventor by the Ministry of Supply.
