...designed to simulate the effect of radar waves on different surfaces (CentannialOfFlight.gov). this was a marked advancement in stealth technology, because for the first time scientists realized that utilizing faceted surfaces, they could scatter almost all radar waves the hit an object away from the source thus making the said object invisible to radar detection, or nearly so. In 1977, this discovery was utilized in a new airframe for the F-117 Nighthawk. This new plane was designed entirely to avoid enemy electronic detection. With a revolutionary faceted design coated with RAM, or radar absorbent materials, the new plane was near-invisible to radar detection, and a new type of exhaust system lessened the heat trail coming from the plane’s engines, making for the first time an aircraft with a minimal infrared signature in addition to its minimal radar signature.

- The first well known example modern stealth bombers and fighters is the Horten Ho 299. The Horten was actually designed back in the 1930s, by the brothers Reimar and Walter Horten. They had become very interested in a “flying wing” design as a way of improving gliders and “eliminating unneeded surfaces”, therefore reducing drag. In 1943, Richsmarschall Goring posted a need for a plane that could fly at 1000km/h(620 mph) and carry 1000 kg of a load over 1000 km; the so called 3x1000 project. The Horten brothers thought their design would greatly helpand the stealth fighter was born.... [tags: stealth bombers, military, history, technology, ]

This was not only from the men who went to fight, there were also the elderly, women, and children who felt they needed to go help their faith. This would also make the Muslims who had control over Jerusalem because they believed it was their holy land as well.... [tags: Crusades, First Crusade, Middle Ages]

Manchester describes the ‘Dark Ages’ as a “mélange of incessant warfare, corruption, lawlessness, obsession with strange myths, and an almost impenetrable mindlessness”.

Bearing a distinct and unique culture relative to the time period, some of the values and the customs held during this time have yet to be repeated in history....
