HEAVY OIL AEROPLANE.

SUCCESSFUL TEST FLIGHT. BRITISH JOURNALIST A PASSENGER. (By Telegraph-Press Assn.-Copyright.) LONDON. April 30. Mr Harold Pemberton, the special representative of the Dairy Express, has made the first flight by a journalist in the new German aeroplane Juno IV., which is driven by a heavy-oil engine. Even German newspaper men have not yet been given permission to ascend in the machine. Mr Pemberton made a long flight, in which the speed varied from 120 to 130 miles an hour. “You can smoke,” said Captain Gothe, the pilot, to Mr Pemberton. “You can empty the hot ashes from your pipe on the engine if you like.” The machine took off perfectly, climbed to 2000 feet, and carried out all the normal tests of airworthiness. The oil fuel used on this occasion was produced from German coal, the Germans using a poor surface coal which cannot be profitably marketed, Mr Pemberton sums up as follows: “If an engine burning heavy oil can do the things that I witnessed, then it is not far from the day when similar engines will be used for all kinds of motor transport!” The engine of Juno IV., is of six cylinders, developing 725 h.p. It is claimed that by the use of heavy oil the range of the aeroplane is increased by 47 per cent., the loading iby 100 per cent., while the working cost is less by 65 per cent.
