FLIGHT, NOVEMBER 16, 1933 MADRID LAS PALMAS AIR LINE A comprehensive wireless organisation is being prepared in connection with the establishment of a new air route between Spain and the Canary Islands, to be operated by the L.A.P.E. Company (Lineas Aereas Postales Espanolasj, the organisation which at present operates the Madrid- Barcelona and Madrid-Seville airways. Communication will be effected on both medium and short wavelengths in order to ensure reliable contact even under very unfavour able conditions, following the practice that has been so successfully adopted on the African and fndian air routes of Imperial Airways, Limited. For this purpose the air craft will be fitted with the Marconi dual-wavelength equipment, Type A.D.37A/38A, which is capable of com munication by telegraph and telephone on the wavebands of 40-80 metres and 500-1,000 metres. The short waveband includes the wavelengths which in exhaustive tests proved to be the most suitable for air-and-ground communication in the face even of severe and prolonged electrical storms as experienced in the equatorial zones of Africa and in the fndian moonsoons. The medium waveband covers all the wavelengths allotted by international convention to normal aviation wireless services, and also the 600-metres wave length generally used by ships. For the terminal airport of the projected air route in the Canary Islands a new ground wireless station is to be erected at Gando, Las Palmas. In this station will be installed the latest types of Marconi transmitters, receivers, and direction finders, providing a complete service of medium- and short-wave ground-and-air communication, with wireless navigational aid available on request- For direction finding, the latest type of Marconi instrument, known as the Type D.F.M.4, operating on the Bellini-Tosi principle, is to be installed. U.S. TRANSPORT NOTES As the first commercial transport type plane to be equipped with two-row engines, the all-metal, low-wing Boeing 247-A has been undergoing flight tests at Seattle. Performance figures have not yet been announced. The Boeing 247-A is to be turned over to the United Aircraft & Transport Corporation for executive use. It is identical with the sixty Boeing transports which have been delivered to United Air Lines except for the employment of two-row '" Wasp Junior^" engines in place of single-row " Wasps," for the installation of eight cabin chairs instead of ten, and lor an exterior finish of aluminium lacquer. The twin " Wasp Junior " has a rating of 650 h.p. at 2,400 r.p.m., and at an altitude of 7,000 ft. Work has been proceeding at the Boeing Airplane Company at Seattle on fifteen addi tional Model 247 transport planes, identical with the sixty already in service on the Coast-to-Coast, Pacific Coast and other routes of United Air Lines. Component parts for the planes are coming from the shops, and assemblies are expected to get under way shortly. Delivery of six Lockheed " Orions " to American Air ways within 30 days was completed in October by Lock heed Aircraft Corporation, Burbank, Calif. Claimed to be the fastest plane in transport service, the new " Orion " showed a cruising speed of 206.2 miles per hour at 8,600 ft., during tests conducted by Marshal Headle, factory test pilot. The superspeed " Orion " is equipped with a supercharged " Wasp S1D1 " engine, and has an estimated top speed of 230 miles per hour. On delivery of the last Orion " from Burbank to American Airways' southern division headquarters at Fort Worth, Headle maintained an average cruising speed of 207 miles per hour. Substi tution of a trailing antenna for a radio mast gave the " Orion " 7 miles per hour additional speed. The first model, equipped with a mast, had a cruising speed of only 200 miles per hour. Construction of this company's bi-motor passenger air liner, the all-metal " Electra," is nearing completion at the Burbank factory. Carrying ten passengers, two pilots and a load of mail, the new " Electra," powered with two supercharged " Wasp Junior " engines, will have a top speed in excess of 200 miles per hour, according to wind- tunnel tests. The landing gear will be retractable. The first of the new " Electras " is scheduled for delivery to North-West Airways of St. Paul, Minn., during this month, and two more planes are due for completion shortly (hereafter. AIR SERVICE TO MAJORCA IT is hoped that within three weeks an air service will be started between Barcelona and Majorca. It will be run by the Compania Aerea Mediterraneo, whose offices are in Barcelona. Dornier " Wal " flying-boats, built in Italy, will be used. The service will be twice daily, and the flight will take about 60 min. Passengers leaving Victoria Station, London, at 11 a.m. and arriving at Barcelona at midday on the following day, will be able to continue their journey to Majorca at 3 p.m., which leaves time for lunch before leaving Barcelona. NEW CENTRAL AMERICAN AIR SERVICE A WEEKLY mail and passenger service will soon be in operation between San Jose, the capital of Costa Rica, and Port Limon. Preference will be given to mails for Port Limon. A FINLAND-ESTHONIA SERVICE AN air service between Stockholm and Revel (Tallin), via Helsingfors, has recently been inaugurated by the Finnish Aero O/Y Company. SUSPENSION OF SERVICE TO EASTERN ASIA OWING to the interruption of various connections in the Soviet system of air lines, and the closing of the Berlin service, during the winter, the aerial connection between Germany, China, Japan and Manchuria was dis continued on November 1. SIXTY OF THEM IN SERVICE : A striking night photograph of one of the United Air Lines' new three-mile-a- minute Boeing 247 transports, halting briefly at Salt Lake City in the course of a Coast-to-Coast flight of less than 20 hours. All 60 of the new Boeings ordered by United, now are in regular service on the company's Coast-to-Coast, Pacific Coast, and other routes. 1153
