AVIA TION BY JOSEPH S. EDGERTON. LL skyways lead this week to Chicago, where on Sat- urday and for nine days following the aviation world will make carnival at the National Air Races over Curtiss- ‘Wright-Reynolds Airport. From this and every other sec- tion of the country and from many foreign lands will come planes and pilots to compete in the biggest air show in United States history, for prizes totaling more than $100,000 and the glory that goes with the modern flying machine. The foreign pilots and ma- chines are attending the annual air show for the first time in sev- eral years. Those from abroad represent the pick of the major powers. Forty-four events have been approved by the National Aero- nautic Association, sponsor of the show, exclusive of the air derbies which will represent every corner of the country in Chicago — one, the Dixie Air Derby, to be started from the Capital during the week. Civilian Pilots Predominate. More than ever before the civil- fan pilots will dominate the show, which in years before has seen most of the laurels taken by fly- ers of the Army, Navy and Ma- rine s. Five of the events listed are closed to civilian flyers. They are the Marine Corps closed-course race; two Army closed-course races, a race for National Guard fiyers for the National Guard Lib- erty Engine Builders' Trophy, and the Navy closed-course race. ‘The rest of the contests are open only to civilians or are free- gor-all, including service entries also listed in the show's sm!nm for three different classifications of motorless planes. ‘The widespread interest in this form of flying, which has grown apace in the past year, is reflect- in the addition of these events to the race pro{nm. ‘The nature of the fleld, flat and without the usual terrain ‘about it for ideal glider flying, will naturally cause these features to appear some- what tame from the spectators’ standpoint. Many interested in gliding, however, believe the time is not far distant when the glider fiyers will have their own show on an extensive scale and in the proper setting for the showing off of the skill of pilots and the excellence of craft. Three of this year's glider events are endurance tests, while :he other two are for spot land- ng. Foreign Pilots to “Stunt.” ‘The foreign pilots attending the show are not expected to com- pete in the Thompson Trophy race. It was with the idea of re- viving the sort of competition af- forded by the Pulitzer Cup races that the magazine Aero Digest fostered the idea of bringing the foreign pilots to this coun- try for the show. For that pur- e Alford J. Williems, former avy flyer and regarded as one of the best speed and stunt pilots in the world, was sent to Europe to IPLAN TWO AIRMAIL LINES ACROSS U. . Post Office Department to Link New York and Atlanta With Pacific Coast. apping out the middle and south- er‘l‘ mnx' lines for transcontinental airmail service, the Post Office De- partment has advertised for bids on a route from New York through the central part of the country to Los Angeles, and another from Atlanta, across Southern United States to the same terminal in California. The two new contracts, to be awarded following the opening of bids at noon on August 25, will do more than add some 4,600 miles to the air. mall network of the country. The Toutes will provide direct access to cross-country mail service by plane. for many important population centers in the Southern part of the country that heretofore have been obliged to send their mail over long connecting links to the New York-Chicago-San cisco line. One Line Across Continent. A glance at the present airmail map shows that North and South lines are far in the lead in number of routes. On the coast there is a line from New York to Atlanta and Miami, Chicago also is linked with Atlanta, mail is carried from Chicago through Kansas City to Houston and to Brownsville, Tex, and on the West Coast there is & line extending from Los Angeles to Seatile. Against these there is one transcon- tinental line, but this line has consis- tently held the poundage record. The New York-Chicago line of National Transport and the Chicago-San Fran- interest the foreign pilots in the Chicago show. ‘He has received acceptance from Flight Lieut. R. L. Atcherly of the British Schneider Cup team of last year and winner of the King's Cup race in 1929; Marcel Doret, lead- and civilian entries. The other events scheduled on the program and already given the p ‘of uaprovll of the Na- tional Aeronautic Association are: Twenty-seven events solely for eivillans, including many free- for-all; open cockpit and cabin lane contests; a dead-stick land- test, balloon bursting event, end a transport and efficiency test; five contests open only to women; five contests for “sports- men” and their planes, and a parachute jumping event. The main event of the show, which is the chief attraction of foreign flyers, of course, is the ‘Thompson Trophy Race for speed lanes which are expected to give he world something new to think about in the way of airplane speeds. It has attracted the best of the planes made in this coun- try and will furnish strenuous competition for the American flyer who would win it. Restores Spectacular Event. The restoration of a race of this sort to the program after a lapse o}{ severta] years assures th: show the mos sort of exhibition whm has been able to offer large assembled crowds. The Thompson Trophy race re- stores racing to the place of im- portance it should have on the program of such an outstanding aeronautical event as the Nation- show, for there has been no su- preme test for plane speeds in several years. In the past the National Air Races have meant a mere on hand, the Grat ishing her world flight, a stunt team and some freakish With the return, however, of the speed race as the major fea- ture of the show, the public has shown a greater interest in the proceedings and the exhibit has gained a public favor that it has not received in several years. Carries $10,000 Prize. ‘The Thompson Trophy carries ‘with it $10,000 for the winner, and this has been no small induce- ment to the flyer and plane man- ufacturers, although the prestige to be gained from such a race is worth considerably more than that to the plane manufacturer who builds the winning ship. There are five glider events AIR LEGION ANNOUNCES NEW AID FOR FLYERS Crash Board Will Assist Any Mem- ber Who Has Forced Landing or Crack-up. A crash board, to proceed imme- diately to the assistance of any member who has had a forced landing or s erack-up, has been named by the Dis- frict of Columbia Air Legion, it was announced today by T. J. Waggy, man- ager of the legion. Lieut. W. C. Buell has been named chairman of the board, and with him will serve Mr. Waggy and Charles Glad- hill, with Miss Harriet Sackett and Ted Kreis to serve as alternate members. All members of the board are licensed pllots. They have been instructed to make & thorough investigation of all crashes and forced landings and to make such recommendation upon them 88 _they see fit, Mr. Waggy also announced that Lieut.

They will, however, do a great deal of exhibition flying for the folk who attend the show to gasp and wonder at, and will contrib- ute all they can to make the show a success. Aircraft Industry Grows. An Interesting survey of the aircraft industry, based on the past year’s trends in production and junking of planes, is issued today by Air Investors, Inc., an aviation investment concern. The survey finds that increas- ing patronage—a patronage that is growing by leaps and bounds— forms a sound basis for optimism over the future of aviation in this country, despite the fact that plane manufacturing shows a de- crease during the year. Aeeordlnf. to the su there were in this country on January 2, 1930, 9,767 aircraft licensed and identified by the Department of Commerce, as against 9,524 on July 1. During this period, the survey states, approximately 1,500 new planes were first licensed and identified, with about 1,740 going &lll: of service during the same e. ‘The downward trend of aircraft e e Surve e of Mm:’muul ber of Com- Engine production to 2,052, against 3,826 in half of 1929, Mail Service Expands. The upward climb of the air mall service, however, is seen as 2 healthy indication for the avia- tion industry. In spite of a gen- eral business depression and un- bad flying weather condi- tions last Winter, the air mail poundage has shown a healthy growth. A 37 per cent increase for the year ending June 30, 1930, the year ending June 30, 1929, is reported, showing con- clusively, the survey states, that the American public is more and more going in for this sort of mail transportation, despite bad business conditions. Quoting the magazine Aviation, the survey points out that pas- senger traffic in March, 1930, was 65 per cent greater than in No- vember, 1920, and 87 per cent greater than in October, 1929, months which were compared be- cause of their equality with re- spect to seasonal influences.

Chicago and Cleveland. Another joins it at Cheyenne, Wyo., and all of the North and South lines, of course, are linked with the cross-country routes. One line, thus, has borne the burden of moving the mail across the country. But it could not be hoped that one route would serve with the best possible efficiency in such cases as for mail or ting in Florida and bound for California. The Southern cities have been pleading for additional air- mail service for a long , and the present additions will answer their Tequests. Bids in Two Forms. Contractors bidding on the routes will do so under the terms of the new Watres law, which specifies that the Post Office Department may, if it sees fit, award the contract to the lowest responsible bidder who has owped and operated an air transportation service on & fixed daily schedule over a (- tance of not less than 250 miles and for a period of not less than six months prior to the advertisement for bids. Bids for both the projected routes must be submitted in two forms—one for the small-space provision of the law and the other for the large-space provision. In other words, the Govern- ment may contract for 25 cubic feet of space to accommodate 225 pounds of mail at & rate not to ex 40 cents a mile, or for 47 cubic feet of space to accommodate 423 pounds of mail at a rate not to exceed $1.25 a mile, In either case it is expected that the lane will carry passengers in addition mall, and it 18 required that planes the small loads must have ca- ity for 10 persons and those with ffif larger loads places for seven. Flexible Rates Charged. ‘There are slight variations from this Tate. Larger payment is made for , an addition of 15 cents a allowed. Two cents a mile for flying over mountain- ous, 214 cents for fog flying, 3 cents & mile if the plane carries one- way radio and 6 cents a mile if it car- Ties two-way radio. In the case of the two new transcontinental mail routes, it is requited that all of the planes have two-way radio. ‘The contracts may be awarded, of course, to any operators who qualify by meeting the requirements of the Post Office Department and by winning in the competitive bidding. . For the cen- tral route from New York to Los An- geles the strongest contender is & com- bination of Western Air Express and :hmoontmanul Alr Transport-Mad- ux. May Hasten Merger. It has even been suggested that the bidding on the route might serve to bring to completion a merger officials of the two groups were sald to be con- sidering. W. Irving Glover, Second As- sistant Postmaster General, in ci of airmail, has said, however, that the two companies may submit a joint bid without in any way affecting their status as individual concerns. ‘The route of this line, as mapped out by the Post Office Department, is as follows: New York ctgflm Philadel- phia and Pittsburgh; lumbus, Ohio; sas City, Mo.; Amarillo, Tex. (or from St. Louis via Tulsa to Amarillo, either or both routes), and Albuquerque, N. Mex., to Los Angeles and return. miles. ‘Western Air Express now carries pas- sengers over the part of this route be- tween Kansas Oity and Los Angeles. The company is also an airmail op- erator, transporting mail between Los Angeles, antl Salt Lake City. T. A. T.- Maddux carries passengets from Colum- bus via Kansas City to Waynoka, Okla., and from Clovis, N. Mex., to Los Angeles on its alrmail system. Most of Route Covered. Thus the two companies together are experienced in flying the entire route, except for the section between Colum- bus and New York. This section is the most_difficult of all, since it involves fiying over the treacherous Alleghenies, Another line which comes into the picture is Pittsburgh Airways, now op- erating with passengers from New York to_Pittsburgh via Wilmington, Del. ‘The sout route is from Atlants via Birmingham, Ala.; Dallas, Fort Worth and El Paso, Tex., and via such points in New Mexico and Arizona as may be designated, to Los Angeles and return, approximately 2,008 miles one way.
