bgo FLIGHT PEOPLE interested in air affairshave for some tim& past knownthat A. V. Roe, Ltd., are con- cerned with producing two separate types ot aircraft specifically designed for passenger traffic of the immediate future. The two aircraft are respectively designated Tudor I and Tudor II, but are conceived for different spheres of operation ; beyond this, suffice to say that we in Britain can look forward confidently to getting at least two types of civil aircraft into the ^ air very shortly which can be expected more than to hold their own with anything that our international competitors can produce against them. It has long been the contention of Flight that, given the oppor tunity, the British aircraft industry can produce in a shorter time than possibly any other, aircraft that can stand unbeaten against all comers. With the advent of the Tudor I it would seem to be established that our contention is eminently justifiable. Mr. Roy Chadwick and his design team have an outstanding record, not only for superlative aircraft but aircraft which are very easy to produce; and it must be stressed that the im- of the latter quality is only slightly less peace than it is in war. Aircraft design years been steadily progressing from the art into that ot science; nevertheless, to a designer's technical ability must be wedded, if his work is to be of any real use, a great measure of common sense—that is to say, he must keep a very sensitive finger on the pulse of practicability and simplicity. In this connection it can, we think, in all fairness be said that Mr. Chadwick is probably the most common-sense designer in his field.

The Tudor I, which bears the manufacturer's designation Avro XX, is very much a single- purpose aircraft, that purpose being to transport in absolute luxury a small number of passengers over great distances at high speed. It is, in fact, expressly suited to the North Atlantic non-stop run between London and New York or London and Montreal. Quite obviously where operation of this nature is concerned, it would be extremely foolish to disregard the advantages latent in high-altitude flight, for it is only where really long-range, non-stop flights are the rule that high-altitude
