Space Shuttle Discovery, Steven F. Udvar-Hazy Center, National Air and Space Museum, Washington DC, America - This was the third of the five shuttles built in NASA's Space Shuttle program preceded by Columbia and Challenger. In 27 years of service, it launched and landed 39 times, having more spaceflights than any other spacecraft to date. Discovery launched the Hubble Space Telescope. On the underside of the shuttle you can see a couple of dark plates, those are new, all the others are worn from re-entry into Earth's atmosphere.
Lockheed SR-71 Blackbird, Space Shuttle Discovery, Steven F. Udvar-Hazy Center, National Air and Space Museum, Washington DC, America - The SR-71 served with the US Air Force from 1964 to 1998. Only 32 SR-71s were built. This plane was not a fighter, it functioned for aerial reconnaissance at tremendous speeds and altitudes, which enabled it to outrace threats, such as surface to air missiles. The plane was designed to have early stealth characteristics and served as a precursor to future generations of stealth aircraft. The SR-71 still holds the record for speed, at 2,193 mph.
