Retrotechtacular: Field Assembling Airplanes Like Wartime “Ikea”

Imagine it’s 1943, and you have to transport 1,000 P-47 fighter planes from your factory in the United States to the front lines in Europe, roughly 5,000 miles over the open ocean. Flying them isn’t an option, the P-47 has a maximum range of only 1,800 miles, and the technology for air-to-air refueling of fighter planes is still a few years off. The Essex class aircraft carriers in use at this time could carry P-47s in a pinch, but the plane isn’t designed for carrier use and realistically you wouldn’t be able to fit many on anyway. So what does …read more

The German Space Program That Never Was

A previous post discussed the creation of the V-2 rocket, the first man-made object to reach space. Designed and built at the Peenemünde Army Research Center during World War II, the V-2 was intended to be a weapon of mass destruction, but ended up being far more effective as a tool of discovery than it ever did on the battlefield. In fact, historians now estimate that more people died during the development and construction of the V-2 than did in the actual attacks carried out with it. But even though it failed to win the war for Germany, it still …read more

Acoustic Mirrors: How to Find Planes without RADAR

A lot of science museums and parks feature something called an acoustic mirror. The one at Houston’s Discovery Green park is called the listening vessels. [Doug Hollis] created two acoustic mirrors 70 feet apart, pointing at each other. If you stand or sit near one of the vessels, you can hear a whisper from someone near the other vessel. The limestone installations (see right) are concave and focus sound like a parabolic mirror will focus light.

Just a science curiosity, right? Maybe today, but not always. The story of these devices runs through World War II and is an object …read more
