Explosive rivets, developed by Du Pont after the basic invention in 1937 by two employes of famed German Plane Builder Ernst Heinkel. A high explosive nests in a cavity at the headless end of an aluminum-alloy rivet. When heat is applied to the head by an electric riveting gun, the charge explodes at the other end, forms a "blind" head, sets the rivet. Explosive charges can be controlled to adjust the size and shape of the head to within .02 in. This breaks a major plane-building bottleneck: riveting points which can be reached from only one side...

...Prince of Wales and King George V; three torpedoes launched from aircraft, two from destroyers, one from a battleship and three from cruisers; and about three hundred 8-in. shells, 4.7-in. shells and other small stuff. PArtly this wonderful shock-worthiness was due to her thick, modern alloy-steel armor, partly to an intricate system of cellular compartments, "blisters," "torpedo bulkheads" - all contributing to her great 118-ft. beam and calculated to isolate and minimize each hole in her skin. But the crew's faith in her buoyancy was betrayed. The British rescued about 100 of them...
...from two shillings twopence (43?) to one-and-ten (37?), then one-and-six (30?), then one-and-twopence (23?), and finally, last month to one shilling (20?) -enough to buy about a pound of stewing meat. More immediately serious is a shortage of certain minor essentials such as alloy metals, which meant that the British Army was going to have to be satisfied with brittler steel in its tanks...
...Michigan land, their chimneys, tanks, furnaces, conveyors, cranes sprouting into the cold Michigan sky, men were beating ploughshares into swords-$122,000,000 worth. Already rolling off the bus assembly line were ugly, buglike reconnaissance cars ("Blitz Buggies") for the Army. Already in limited operation was a magnesium alloy foundry, turning out lightweight castings for airplane engines...
