Shell Speed Dashes
SHELL PETROLEUM CORPORATION, St. Louis, Mo., is again sponsoring a series of official three-kilometer straightaway speed dashes for a new world landplane record. Inaugurated at the 1932 National Air Races, this feature resulted in the setting of the existing world mark for maximum speed when Maj. James H. ("Jimmie") Doolittle, former Army flier and manager of the Shell aviation department, put his barrel-like Gee Bee over the course at an average of 294.38 miles per hour.
Shattering of this record is confidently expected with the $2,000 purse posted by the Shell corporation as a prize at which to shoot. The builders of several high speed ships that failed to reach Los Angeles have bent every effort to eliminate the "bugs" that kept their planes out of the national meet. One of these ships is reported to have a high speed of 360 miles an hour. Another has shown 275 miles per hour at three-quarters throttle, and engineers estimate its minimum speed to be 340 miles an hour.
