Not Paula Murphy but she was present at the dinner gathering along with a small group of Avanti icons and enthusiasts when the story was told. I'm surprised no one mentioned the Granatellis.
After dinner, Vince Granatelli told how at the end of a speed run he was trying to slow the Avanti as it headed straight toward the Press bleachers at high speed. The Avanti wasn't slowing down and steering on the salt was less than ideal. He was afraid he would wipe out the entire Motoring Press in the stands. He popped the parachute and stood on the brakes and finally managed to stop the Avanti just a few feet from the Press bleachers. Members of the Press thought it was all part of the show and stood up and cheered.
