asked the Secretary of State for Air whether, in view of the successful experiments of the Question Mark in the United States of America in refuelling in the air, he will introduce it into the routine of civil, naval, and military aviation?

Experiments in refuelling aircraft in flight have been carried out successfully at the Royal Aircraft establishment, and the experience thus gained is available whenever it is required. To prescribe this method of refuelling, however, for Service or civil machines, as a matter of routine, if that is. my Noble Friend's suggestion, could hardly, I think, be regarded as a reasonable or indeed practicable requirement.
