A Swiss daredevil planning to fly above the Grand Canyon in a jet-propelled wingsuit won't know if he's allowed to do so until Friday _ the day of his scheduled flight.
The Federal Aviation Administration says it's still reviewing adventurer Yves (yeevz) Rossy's proposal to ensure it meets safety standards.
FAA spokesman Ian Gregor says a decision won't be made until Friday morning.
The 51-year-old Rossy plans to jump from a helicopter on the Hualapai Reservation, soaring over the Grand Canyon in his first U.S. flight in the custom-built suit.
The reservation lies west of Grand Canyon National Park.
Rossy, who calls himself the "JetMan," has flown over the Swiss Alps and across the English Channel in the suit.
