Flashes: March 26, 1993

MODEL BEHAVIOR: Somewhere Michael Landon is smiling. On March 15, Cindy Crawford accepted an award in his name benefiting the National Children's Leukemia Foundation. ''I never met him, although I was a loyal watcher of Little House,'' says the supermodel, 27, who was 10 when her 4-year-old brother died of the disease. Crawford donates half the cash from her swimsuit calendars to leukemia groups. ''My husband's (Richard Gere) activism rubs off on me,'' she says. ''He shows me how to use my name more effectively.''
