...wing has increased from one-third of total drag to about half. To reduce this the NACA experimented with the friction set up by rivets and lapped plates on the wing surface. A modern plane weighing 20,000 Ib. and having a wing area of 1,000 sq. ft. was found to require 182 less horsepower to reach 225 m.p.h. if its wings were smoothly polished than if it had normal overlapping plates and brazier rivets with a head-diameter of 3/12...
...With airplane size now reaching vast proportions, most airports are becoming obsolete. The NACA has been experimenting with catapults to solve this problem, found that the forthcoming Douglas DC-4 will need a thrust of 15,000 Ib. to take off in 1,150 ft. This requires an engine of 3,250 h.p., which is too expensive. Probable solution will be a large flywheel which can store up this much energy. The catapult would presumably rise from an emplacement in the centre of the field. Passengers might need headrests, but would not be internally distressed by the sudden start...
...Philadelphia Council hearing, Mayor S. Davis Wilson asked Board Chairman Samuel Matthews Vauclain of the Municipal Gas Corporation to support his campaign to reduce Philadelphia's gas rate from 90? to 50 per 1,000 cubic ft.

...gigantic harbor buoy sticking up between two scows. A structure they think improper to the high seas, this is no buoy but one of several oil derricks erected in the bay by Texas Co. Called "deep-sea drilling," Texaco's operations are in water no deeper than 25 ft., but geophysical crews mapping off-shore contours often have to take dynamite soundings. The fishermen claim that any fish not killed or scared clean to Cuba by the explosions are certain to be dispersed by oil-polluted water around producing wells...
