P-51 mustang

1)- The North American p-51 Mustang was the most famous fighter during World War 2 and was highly respected aircraft by both the allies and the enemies. It was built in 1942 and was a fast andcapable fighting aircraft. The P-51 was designed, built and flown in only 117days after the British asked North American Aviation to produce a high performance fighter. Mustangs had the very important jobof escorting bombers deep into Germany. The definitive version, the P-51D, was powered by the Packard V-1650, a two-stage two-speed supercharged version of the legendary Rolls-Royce Merlin engine, andwas armed with six .50 caliber (12.7 mm) M2 Browning machine guns. After World War II and the Korean War, many Mustangs were converted for civilian use, especially air racing. The Mustang's reputationwas such that, in the mid-1960s, Ford Motor Company's Designer John Najjar proposed a new youth-oriented coupe automobile be named after the fighter.
2)- German U-boat attacks on merchants ships inthe Atlantic were a serious threat to the Allied war effort. American Vice Admiral William S. Sims convinced the British to try the convoy system, in which a heavy guard of destroyers escortedmerchant ships back and forth across the Atlantic in groups. By fall of 1917, shipping losses had been cut in half.

But these technological developments have also had far-reaching applications in peacetime. Because theinnovations were originally intended for the battlefield, they were developed quickly and with a narrow purpose. However, their applications during peacetime had lead to life-enhancing benefits that willextend far into the 21st century.
