FLIGHT Twin intakes and twin outlets characterise the Hawker N.7/46 (one R.-R. Nene) Radlett ... Not just another Meteor model, but one showing the new long nose and external tanks. was noticed : whereas originally the four Hispanos fired through ports well forward in the fuselage, there are now two large concave blast channels extending some distance aft. The machine displayed was also fitted with the latest clear-vision cockpit enclosure. Mr. Gibbs put up a really outstanding flying display on the Brigand. Not only did he demonstrate its ability to turn tightly, but he delighted everyone by executing a roll. This is probably the first time an aircraft carrying the war load already mentioned has been rolled in public. While discussing aircraft of this class it is not unfitting to mention the de Havilland Mosquito prototype, shown for the second year in succession. Itself a day bomber, this his- toric machine was dis- played with items of military equipment which the "Mossie" has been developed to carry in its variegated forms. Among these * were two 1,000 lb. rockets. Due to its rela- . tively large size (it has a span of about 60 ft., though the folded width is only 20 ft.) the Short Sturgeon did not, perhaps, convey a true impression of its speed. At 19,000 ft. it achieves well in excess of 400 m.p.h. Some of Mr. Booth's manoe uvres in the Stur- geon produced pronounced wing-tip trails, and his upward rolls suggested that whoever was responsible for the specification might well have included fighting in the list of the Sturgeon's duties^ The reconnaissance version, as demonstrated, is not in quantity production, but the Mark II target tower will be supplied to the Royal Navy next year. Painted to match the civil Hermes II. the Handley Page Hastings impressed not only by its bulk and cleanness of de- sign, but by its re- markably high speed. Together with the Lincoln it represen- ted Service aircraft in the "circus" of multi- engined types which opened the flying programme on Tues- day and Wednesday. To see an aircraft de- signed to carry 25- pounder guns or three- ton lorries, zooming steeply to over 1,500 ft. The new tail unit which characterises the de Havilland Vampire III. is undeniably an en-tertaining experience, and we would not agree with those who maintain that in view of the role of the Hastings suchflying proves nothing. One gathers that a dihedral tailplane is to be fitted experimentally to one Hastings. Together with the Hastings the Valetta, likewise dis-played, will shortly be in R.A.F. Service. Particulars were published in Flight of September 4 and a new flying photo-graph appears in this issue. Visitors to the Valetta—and there were many—noted the transparent panel in one of theloading doors, giving access to fire extinguishers and an axe. These items, of course, are also accessible from inside theaircraft. The fourteen windows are all designed as pull-in emergency hatches. With its inherent safety and such fea-tures as those mentioned the Valetta should soon become popular with the Army. Air Observation Posts ^i#» Last year, it will be remembered, a great deal of interest was occasioned by a model of the Heston A.O.P. mono- plane to specification A. 2/45. This year the prototype was demonstrated in the air, although only a few flying hours have yet been completed. Not even the Heston Aircraft Company design staff would claim that this stilty pusher has beauty, but it does possess other virtues in abundance, notably the ability to take off and land in very confined spaces and to fly slowly; an exceptionally wide field of view; ease of maintenance; and ease of transport. The full-span leading-edge slats and the large slotted flaps form a high- lift system which is considered to be near the optimum for the wing in the take-off case. Higher lift coefficients than those obtained would result in a higher induced drag. The Sea Fury X with wings folded, contrasted with a model of the Wyvern (top).
