Oral Answers to Questions — Civil Aviation. – in the House of Commons at on 22 June 1922.
asked the Secretary of State for Air the number of foreign-owned passenger-carrying aeroplanes trading between their own country and England which carry only a single pilot; what number are not yet fitted with wireless; and whether he can give approximate dates on which these essential improvements are to be remedied?
The SECRETARY of STATE for AIR (Captain Guest):
The answer to the first question is 71 aeroplanes, of which 10 will eventually be replaced by aeroplanes fitted with dual control capable of carrying two pilots; to the second 65; to the third, that it is expected that all these aeroplanes will be fitted with wireless apparatus within the next three months.
