Experiences flying on SOFIA
Early science observations with SOFIA From preparations to installation to science
It has been both challenging and rewarding We are part of a making a highly complex system
work But, of course, that is the point (to push new
boundaries) At every stage things have worked better than
(I) expected

Results
Science flights have been highly successful. 3 Short Science and 10 Basic Science have lots of
publishable results Wide range of programs covering planetary
science, star formation, stellar evolution, the interstellar medium, and others.
