In the meantime three very much larger boats are in course of construction, and the first of these should appear in a few weeks. In general design these " G "-class boats, as they are designated, will be somewhat similar to the " C "- class boats, but will be fitted with four of the new 1,380 h.p. civil-rated Bristol Hercules sleeve-valve radials.

Towards the end of last year the Air Ministry announced that three large landplanes had been ordered from Short Brothers, two for operations at more or less normal heights, and one for high altitude work with a pressure cabin. These machines, again, will be fitted with four Bristol Hercules engines of 1,600 h.p. and are of the high-wing type. The provisional figures for the 14/38 landplane (as the new type is to be known) are: 127ft. 6in. (38.6 m.) 89ft. (27 111.) 1,800 sq. ft. (167.2 sq. m.) 39,0501b. (17,650 kg.) 41,3101b.

MANCHESTER AND THE AIRLINES ALTHOUGH work is still going on in the development of Manchester's new airport at Ringway, trrts is now quite ready for all comers. It was actually opened last summer and, though a full year's working is not yet complete, the traffic, actual and prospective, is being closely watched by the airport committee and it is quite possible that a central office may be set up in the city itself to deal with nothing but airport business. The preliminary announcements of this summer's internal airline plans suggests that Manchester will be quite well served, but both the airport committee and the Manchester Chamber of Commerce think that it should be possible, with Ringway so centrally placed in the country, for travellers to leave Man chester at a reasonable hour in the morning and to make a stay of six or eight hours in any of the larger towns in this country and Scotland, before returning on the same day. Recently the Manchester Chamber of Commerce issued a lengthy memorandum on the subject of airline needs. In brief, the memorandum urged the Government to do something about the old Maybury junction scheme and demanded guidance from the Air Ministry—complaining that the internal air routes have so far been built up without any guiding principle or policy. After explaining the city's airline aspirations, dealing with the Maybury Report, complaining of lack of policy, describing the advantages of Ringway itself, outlining the industrial, commercial and private interests which are awaiting airline facilities, and explaining the need for adequate propaganda for commercial aviation, tne memorandum summarises its con clusions and recommendations on, more or less, the following lines: — (a) The unsatisfactory state of the airlines should be brought to the notice of the Air Transport Licensing Authority, (b) The same authority should prevent any stabilisation of the present unsatisfactory state of the airline system, (c) Individual air line operators should be approached in order that the Man chester potentialities can be explained, (d) Efforts should be made to secure Parliamentary support for the various objects set out in the memorandum, (e) A list should be made of the various firms which might make use of good air services, (f) A special propaganda fund, to which interested parties would contribute, should be established, (g) Such propaganda should be put into action before the opening of the 1939 airline " season." (h) The establishment of a central office in Man chester, the function ot which would be to provide essential information about air travel, and to serve as a freight collection depot (i) Efforts should be made to attract the general public to Ringway by the provision of flying and other facilities, and by improving the communications between the airport and the city.
