[FOTZeiss] Airborne Telescope Prepares for Takeoff

[Glenn A. Walsh]

The large hangar at Site 9 now houses several aircraft used by the space agency for earth and space science research, from a pair of ER-2 planes (the civilian version of the U-2) to a modified 747 known as the Stratospheric Observatory for Infrared Astronomy, or SOFIA, being prepared for science flights to start in the next several months.
