The family of Col. Ilan Ramon will depart today from the United States for Israel. Aboard their flight will be the coffin of their husband and father, Israel's first astronaut, who perished aboard the Columbia space shuttle eight days ago upon its return to Earth. Waiting to greet them at the military airport in Lod tomorrow will be Prime Minister Sharon, Defense Minister Mofaz, and IDF Chief of Staff Yaalon. Col. Ramon will be buried in a military ceremony - for family and friends only - on Tuesday in Nahalal, in the Jezreel Valley.
