2 Air France flights headed from the United States to Paris

"Several law enforcement agencies are working ... to
determine the nature of the threats which caused the
aircraft to divert," FBI Special Agent Todd Palmer of the
Salt Lake City division said.
No U.S. military aircraft were scrambled in either incident,
NORAD spokesman Preston Schlachter said.
"Diversion of flights are the most draconian response to
a bomb threat," CNN national security analyst Juliette
Kayyem said.
Officers searched the plane that landed in Salt Lake City and
rendered it safe, Salt Lake City Airport Police Chief Craig Vargo
said.
He said airport officials have turned the plane back over to Air
France, which was preparing the plane for departure.
