The object of the Red Wing project was "To determine the optimum economic uses of electricity in agriculture and to study the value of electricity in improved living conditions on the farm." Although not the first service to farms in the U.S., it was likely the first built as an experiment specifically for collecting and publishing engineering and economic data.

Lunken Field, now also known as Cincinnati Municipal Lunken Airport, opened in 1925 on ground purchased from the Cincinnati Polo Club. The nation’s largest municipal airport at the time, it attracted several aerospace enterprises, starting with early aviator J. Richard “Dixie” Davis, who established his barnstorming enterprise there in 1925.  In 1928, several other firms established enterprises at the field – each making history.

Newark Airport

In May 1927, the same month of Charles A. Lindbergh's famous transatlantic flight from New York to Paris, a fact-finding commission appointed by the U.S. Secretary of Commerce concluded that Newark would be the ideal location for an airfield to serve the greater New York/New Jersey metropolitan area.

Civic leaders wasted no time; construction began on the Newark Airport in January 1928. Nine months and $1,750,000 later, 68 acres of soggy marshland had been filled and converted to an airport.

At the age of 24, Polish-born mechanical engineer Tadeusz Sendzimir found himself in Shanghai, China, after escaping his homeland to avoid the draft for World War I. In 1918 he opened China’s first nail and screw factory, using jury-rigged drill presses. He spent his spare time walking along Shanghai’s canals and riverfronts, visiting machine shops and scrap iron dealers. He’d bargain in pidgin English with the shop’s assistant while the owner snoozed peacefully in the back, clutching an opium pipe.

Before 1930, refrigerators were not only bulky and expensive but extremely dangerous. Chemicals used as refrigerants—ammonia, methyl chloride, and sulfur dioxide—were not only toxic but highly combustible. In 1929 a leak in a methyl chloride refrigeration system caused an explosion that killed more than 100 people in a Cleveland hospital. It was no wonder that consumers preferred their old iceboxes. That would all change in 1930 with the invention of Freon by a General Motors researcher.
