FLIGHT JANUARY 6TH, 1949 BOOK REVIEWS Aircraft—from Airships to Jet Propulsion. By B. W. A. Dickson. First impression, private issue, then Naldrelh Press. Price &s Gd. HPHIS is the season when the aeronautical journalist must-»• grapple with reviews of progress during the preceding twelvemonth. Having lately been associated in such an under-taking, the writer has a fraternal feeling for Mr. Bonner W. A. Dickson (General Manager, Aircraft Section, Vickers Arm-strongs, Ltd.) who has compiled a record of "V.A.'s" aero- nautical activities since 1908, in which year, co-operating withthe •Royal Navy, the firm began experimenting with lighter- than-air craft.The fruit of Mr. Dickson's researches is a handsome volume, of the above title, lately issued by Vickers, Ltd., and contain-ing a foreword by Major Sir Hew Kilner, M.C., Deputy Chair- man, _Vickers Armstrongs, Ltd. The first copies have beenissued on a restricted scale, but another edition was published through the normal channels on January 3rd.It is to be regretted that the author could not have included some of the many Vickers and Supermarine prototypes which,though never reaching the production stage, exhibited many meritorious design features. Such errors of commission as wehave noted in a preliminary perusal are of a minor nature, though we are constrained to take up Mr. Dickson on his state-ment that "the maximum speed for a straight run of the Attacker has not been disclosed." This has, in fact, frequentlybeen published (590 m.p.h.). German Gas Turbine Developntents during the period 1939-1945. His Majesty's Stationery Office. Price is. AN overall report on German gas turbine developmentsduring the war has now been published by His Majesty's Stationery Office. It is the work of the British IntelligenceObjectives Sub-Committee and is based on a very large number of individual B.I.O.S., C.I.O.S., F.I.A.T., and J.I.O.A.reports. The. purpose of the booklet, which is remarkably concise, has been to answer the question '' what can Britainlearn from Germany? " An introduction deals with early developments and pre-war work, individual projects beingreviewed, but the bulk of material is devoted to component design and material specification and properties. Reference ismade to gas turbines for power generation, marine work and' armoured fighting vehicles, but in the main the report refersto aircraft power units. In an appendix principal data con- cerning the German aircraft gas turbines dealt with areneatly tabulated as shown below. The arrangement of the report is commendable, and forthose wishing to pursue investigations in greater defail, all previous reports and pamphlets from which this summary iscompiled are listed, and an index is provided. - ... Fly With the Pilot. By Alan Buck. Quality Press, Ltd. 7s. 6d.T HAT Fly with the Pilot has been written for school-agers is immediately apparent from the large, well-spaced print,, but so interesting and informative is this little book that many an adult as yet uninitiated into the elementary technicalities of flying will find it well worth an hour or so of his leisure. With the promise of a flight in a B.O.A.C. airliner ahead of him, the reader first learns something of the principles of flying and receives his bapteme de Vair in a light aircraft. Then comes the flight in a Lancastrian from London Airport and subsequently another in a flying boat at Hurn.^ During these trips the reader is "at the pilot's side" and has every phase of flying procedure explained to him in simple terms. - Manu- facturer Junkers B.M.W.
