In October 1925, crowd gathered to watch the Pulitzer Trophy air races at Mitchel Field, Long Island, New York. VIPs arrive in various automobiles. Army Air Service Curtiss R3C-1 airplane is pushed onto the field. Air Service Chief, General Patrick , speaks with Lieutenant Cyrus Bettis as Lieutenant James Doolittle listens. A Navy crew works on their entry in the race, similar to the Army Air Service airplane. Navy Lieutenant Al Williams seen with a pipe upside down in his mouth. Lieutenant Bettis taxis out for takeoff in his airplane number 43. Then Navy Lt. Williams proceeds to take off in his aircraft, number 40. Lt. Bettis breaks ground and begins to fly the closed course, coming very close to the ground at times. He lands and climbs out of the cockpit, surrounded by spectators and officials who are convinced he has won, registering a speed of 249 miles per hour. Navy Lt. Williams lands shortly thereafter having averaged 242 miles per hour. He is greeted by several spectators, including a young woman.
Two weeks later, the U.S. Army was represented by Lieutenant Jimmy Doolittle, who flew the Curtis R3C-1, again, but this time fitted with floats, at the Schneider Cup Seaplane Race in Baltimore, Maryland. He shakes hands with a young woman, just before the race. The Navy also entered with a similar seaplane, shown being pushed into the water. The British entry, a Glouster-Mapier IIIA is seen (replacing the Supermarine-Napier S.4, that was damaged). The Italian Macci M.33 is seen on a dock with engine running. The float planes taxi out over the Chesapeake bay waters to takeoff position. Doolittle is the first to take off and to return, logging an average speed of 232 miles per hour.

Using a beaker labeled crude oil, a man demonstrates that it yields petroleum products of 30% gasoline, 20% kerosene, and 42% lubrication oil and wax, and 5% coke. Animated diagram shows layers of rock and wells being drilled to various depths to tap oil reservoirs, avoiding water pockets. Another chart shows successive layers of natural gas, oil and salt water that may be encountered. On the surface, the boiler, mud pond, derrick, engine and pump are identified at drilling site. Well casing, drill and movement of drilling products are illustrated.
United States Army Air Force footage of a helicopter designed by Emile Berliner and Henry Berliner being tested in Washington D.C.,United States. This was one of the final Berliner models built, if not the final, constructed after the triplane model 5 variant that had been demonstrated in February of 1924. This variant had a biplane configuration and was lighter to improve the thrust to weight ratio. The lower wing generated lift from the rotor downwash due to a high angle of incidence and large camber. The helicopter repeatedly lifts off, hovers, does some forward movement, and then touches the ground.
