Jill and her parents lived in the Vista Las Palmas home from 1960, when the futuristic house with its circular rooms and jet-wing roof was constructed, to Nov. 14, 1965, when Bob and Helene — along with Bob’s parents, George and Mildred — boarded a private Lear jet that, shortly after taking off, slammed in to the San Jacinto Mountains during a thunderstorm. And just like that, as Carrie Bradshaw might say, everything changed. Jill, at 13, went to live with her aunt and uncle in Los Angeles.
