Odd Facts on Pringle Sanitation and 1940s Tech
An 18th century physician Sir John Pringle is called the father of military sanitation for his exhaustive study of health problems of soldiers, published in 1752. The text notes U S service ceilings for airplanes rising from 25 060 feet in 1918 to 45 000 feet in 1944 along with increases in horsepower and bomb loads. It mentions an old word for iron be nipe possibly meaning meteorite, and lists aviation speeds from 130 mph in 1918 to 450 mph by 1944. It also cites the steel industry's 1944 employment average of 571 000.
