The legendary Convair B-58 Hustler, one of the most interesting bombers to reach operational status, and had an appearance - even though designed in the 1940s - that would not look out of date in the 21st century. The first USAF delta-wing bomber was the Mach 2 Hustler that had the performance of a fighter aircraft. However, its tenure was short due to technical problems and excessive costs. The majority of Hustlers met their demise in the late 1960s, but a few remain at museums across the country.
