THE SUNDSTEDT-HANNEVIG SEAPLANE.
  
  At the plant of the Wittemann-Lewis Aircraft Co., probably one of the largest seaplanes in the United States has been constructed by the prominent Swedish aviator, Captain Hugo Sundstedt, and the well known Norwegian financier, shipbuilder and shipowner, Mr. Christoffer Hannevig.
  Captain Sundstedt is one of the pioneers in aviation, having flown since 1910. In July, 1914, just before the war broke out. ho made a non stop flight from Bue, near Paris, France, to Stockholm, of about 1,200 miles, in a Henry Farman biplane, in 13 hours and 20 minutes. During the war Capt. Sundstedt has been about two years in France, and received several decorations. About three years ago he left France for the United States for the purpose of building an aeroplane for a trans-Atlantic flight.
  The Sundstedt-Hannevig seaplane has been designed for the specific purpose of long-distance flying over the sea. In general, it has been designed with an extra heavy substantial construction, particularly an those parts subjected to the greatest amount of strain during flight and at landings, such as pontoons, wings, and the entire rigging.
  In the design, however, only proved aero-dynamical principles have been embodied, assuring a positively efficient machine, and Captain Sundstedt has made a large number of improvements in structural details, affording the utmost strength and lightness of construction.
  The seaplane is equipped for two pilots and two passengers in the cabin of the fuselage. General Dimensions.

The Transatlantic Flight

  CAPT. HUGO SUNDSTEDT, who is engaged in assembling a seaplane in Newark Bay, New Jersey, as mentioned in our last issue, has now made a formal entry for the Daily Mail ?10,000 Transatlantic Prize. This makes the fourth actual entry, the others being a Whitehead entered by Capt. Fayze and a Handley Page and a Caproni entered through the Aero club of America.
  Lord Auckland, who arrived in Liverpool recently from America, stated that he intends to attempt an aerial flight from Britain to the United States next August on a British machine. He expressed the firm conviction that an air journey to America is possible, but thinks the time is not yet ripe for a continuous service between the two countries.

The Transatlantic Flight

  CAPT. HUGO SUNDSTEDT made a test flight with the machine entered for the Daily Mail ? 10,000 prize on February 21. He had proceeded a mile over Newark Bay, N.J., when engine trouble developed, but he expressed satisfaction with the way in which the machine answered the controls. Further tests will be carried out before an attempt is made made to fly to St. John's. Newfoundland.
  It has been announced that Capt. Roy Francis who is in charge of the plans of the U.S. Army for an attempt to fly the Atlantic. He has been installed in the Trant Company Institution, formerly the headquarters of Count Bernstorff's propaganda department.

THE TRANSATLANTIC FLIGHT

  DURING the past week no further entries have been received for the Daily Mail prize, and the number of probable competitors has been reduced by one owing to the accident to Capt. Sundstedt's flying boat. It appears that the machine was taken out by Comdr. Czenzki, a Russian pilot, and failed to come out of a spiral 400 ft. up.
  Some comment has been caused by the abstention of the French makers, but it is likely that unless the prize is quickly won there will be a t least one or two competitors bearing the French colours. It is an open secret that one of the leading firms has been experimenting to this end for some time, but no definite entry will be made until everything is ready for the attempt to be made.
  Mr. Hawker and Capt. Grieve, with the Sopwith aeroplanes, arrived in St. John's, Newfoundland, on Sunday, and they are making their preparations to start at 2 p.m. on April 16, in order to take advantage of the full moon, if the weather conditions are favourable.
  Mr. Raynham and Capt. Morgan, with their Martinsyde, are now on their way to St. John's. A series of thorough tests, including a ten-hours flight, during which the machine flew from Woking to Southampton and back five times have been made. The "Raymor" has a span of 41 ft., and is 26 ft. long. It is fitted with a 285 Rolls-Royce "Falcon" engine and, carrying 375 gallons of petrol, the weight will be about 5,000 lbs. Capt. Morgan only recently returned from Newfoundland, where he was making preliminary arrangements. It is hoped to make a start towards t he end of April.
  The Fairey seaplane will be of the 3C type - a biplane having a span of 46 ft. 6 ins. and an overall length of 36 ft. It will be fitted with a 365 h.p. Rolls-Royce "Eagle" engine, and will carry 385 gallons of petrol, sufficient to carry her 17 1/2 hours a t 120 m.p.h.
  The Short biplane will be of the Shirl type, having a span of 62 ft. and an overall length of 37 ft. It will be fitted with a 385 h.p. Rolls-Royce "Eagle" engine. The 650 gallons of petrol will be carried in a torpedo shaped tank 18.ft. long and 3 ft. 2 ins. in diameter slung beneath the fuselage. It is expected that the machine will be ready for a trial at Gosport in a few days.
  The machine will be painted white, with a Union Jack on the tail. Major J. C. P. Wood, the pilot, and Capt C. C. Wylie assistant pilot and navigator, will sit one behind the other. Their equipment will include electrically heated boots, jackets and gloves and they will also wear special long-distance helmets fitted with wireless telegraphic receivers, all of which are being thoroughly tested before the start. The system of directional wireless will be used and the pilot and navigator will receive messages from the Air Ministry every half-hour.
  The U.S. Naval authorities have decided that they cannot compete for a prize given by private enterprise. Nevertheless, the arrangements are being pushed forward for a flight by naval machines - probably three flying boats of the N.C.1 type.
  According to t he Aero Club of America, a cablegram states that the Air Ministry is considering the Club's invitation to fly one of its airships across the Atlantic to the Pan-American Exposition at Atlantic City in May.
  A message from New York states that the British officials in charge of the projected flight from Newfoundland to England say that they may carry several letters from that country, but the cost will be L100 each. The letters must not exceed one ounce in weight each, and the number is limited to 12. Inquiry has not thus far revealed that many Americans are anxious to spend L100 to send a letter to Europe by aerial mail.

Captain Sundstedt's seaplane as seen from behind, upon which he contemplates making a try for the Trans-Atlantic #10,000 flight prize of the Daily Mail. The wings of the 'plane measure 100 ft. It is equipped with two 400 h.p. Liberty motors, and is capable of a speed of 80 miles an hour. The cabin, which is completely enclosed, will hold four passengers. The two tons of petrol needed for the flight will be carried in the tank in the huge tail of the machine. The 'plane, without its passengers or fuel, weighs 10,000 lbs. Captain Sundstedt will fly from Bayonne (N-J.) to St. John's, Newfoundland, and from there attempt the flight across the Atlantic. He hopes to make the journey in 22 hours. The distance between Newfoundland and Ireland is about 1,800 miles.
