    Leslie A. Whittington, of University Park, was on her way to Australia with her family -- her husband of 17 years, Charles S. Falkenberg, and their daughters, 8-year-old Zoe and 3-year-old Dana.
    Whittington, 45, an associate professor of public policy at Georgetown University, was to be a visiting fellow for two months at Australian National University in Canberra.
    According to Georgetown's Web site, she was "an economist who has research interests in public finance, labor markets and family policy." She wrote extensively on the personal income "marriage tax" and the problems it created for families and was co-writing a book about women, work and family.
    Falkenberg, 45, was the lead software engineer for ECOlogic Corp. in Herndon. For the last six years, he had worked on developing "scientific data delivery systems" for oceanographers, ecosystem scientists and space scientists, according to his biography on the Internet.
    He had worked in Alaska developing a software system for researchers evaluating the long-term effects of the 1989 Exxon Valdez oil spill. When he died, he was at work on a project for NASA.
