New York, Oct. 7—Experts_ of the Army and Navy Aviation. Service to-day were preparing reports on the demonstration of a flaming oil-soaked, fire-proofed airplane and its midnight landing device, witnessed by them at Mineola. ''American and British experts who saw the spectacular demonstration by Paul Colins, a civilian flyer, said it marked one of the most important developments in aviation since the armistice, Before making an ascent to an altitude of 5,000 feet Collins's machine was treated throughout with the fire-proofing "dope" and then completely saturated with gasolene. Collins himself donned a costume similarly treated. At his highest altitude he set fire to the gasolene and thrilled the countryside by his flaming, comet-like course. At about 1,000 feet he touched off two large flares of magnesium, on the tips of the wings and, by manipulate ing two large mirrors underneath the fuselage, he illuminated the whole landing field, enabling him to make a perfect "daylight" landing.
