Another amazing aircraft was the SR71 Blackbird. Sad to see it deactivated but I understand at least 3 could come out of mothballs when needed.
Surprisingly, the U2 Dragon Lady is still around and used for reconnaissance and surveillance missions. But I heard the Global Hawk may replace it in the near future. Here is a pic of a U2 way up there in altitude probably around 70,000 feet but the exact altitude capability is classified. My son is an aviation mechanic in the U.S. Air Force and works with the U2.
