"Like many American families across the country, the Stern family of Colorado celebrated the Fourth of July holiday together on Sunday. But instead of a traditional barbecue or picnic, the family took to the skies for a novel weightless daytrip on a Zero Gravity Corporation (Zero-G) aircraft. Here, journalist and eldest Stern daughter Sarah Stern describes the experience of the July 4th trip, which was arranged as part of a project led by her father - planetary scientist Alan Stern - investigating the scientific uses of zero gravity and suborbital spaceflights at the Southwest Research Institute."
