Since 2015 Everts Air has operated a Boeing 727-227F for the Zero Gravity Corporation (also known as ZERO-G), which previously operated with Amerijet International. The aircraft is based in the Contiguous United States and operates weightless flights. Unlike NASA, ZERO-G is governed under Part 121 of FAA regulations, enabling the company to cater to both tourists and researchers alike.
