SPEED IN THE AIR
LIMIT OF 700 MILES AN HOUR. { LONDON,. September, 20. I The greatest spe/ed attainable by the present type of aircraf.t, Prqfessor H. E. Wimperis tefdpthe; British Science Congress, will be'7oo miles an hour. If any greater-speeds were attained, said the speaker, it- seemed that .they would only be accomplished by using exceedingly (thin,’ * 'foils.Speeds much higher than; those now usual could, be found by ■ deserting the Schneider Trophy levels; and ascending:to'altitudes of 20,000, 50,000, or even 100,000 feet. “But to fly near the ground at much above the present record of 407 miles an hdur must be almost impossible without a drastic change in areoplane construction,” continued the professor. “Perhaps 50 or 60 miles an hour more could be obtained by the introduction of some such device ,as changing the wing-area while in flight- or using flaps or slots to reduce landing speed.” Professor Wimperis, the Director of Scientific,;Research inrthe Air Ministry of /Britain since 1925, has been identified with the study of aeronautics for many years. . _
