It was reported yesterday that the U.S.-German joint NASA-DLR SOFIA airborne observatory saw (nighttime in-flight) first light on May 26th. These images of the 2.5-meter, 17-ton infrared telescope and the much modified Boeing 747SP aircraft are credited to NASA/Dryden, Tom Tschida from May 20th (left) and Jim Ross from April 14th this year.
