...against most ordinary ocean blows. But the one that whistled in on the afternoon of last September 21 was no ordinary blow, it was the wildest in the memory of any New Englander.

It resembles nothing more than a woven basket covered with fabric to keep out the breeze, powered with two 50-h.p. engines to pull it through the air. Its structure is called geodetic because the Greenwood-Yates ribbing is laid entirely in curves...
...what NACA has done since the doors of the laboratories were last opened to visitors two years ago. Because this year's NACA discoveries will be flying in next year's military airplanes, only U. S. citizens were invited, their cameras were parked at the GHQ Air Force headquarters on the field and they were warned to make no sketches of charts or equipment...
NACA's research director, Dr. George William Lewis, was proudest of a new wing developed during the past year. Approximately one-half the drag, i.e., the speed-killing characteristic, of the modern airplane is caused by its wings. Most of the wing drag is caused by air friction along the surface which, as the plane speeds through the air, changes from a smooth or laminar flow near the leading edge to a tumbling, churning turbulence farther back on the wing...
