>From the SF Chronicle:  A United Airlines jetliner carrying 45 people
crashed into a grassy field on Tuesday morning, minutes after a man who said
he was a passenger told an emergency dispatcher in a cell phone call: "We
are being hijacked, we are being hijacked!"
A Virginia congressman said the plane's intended target was apparently Camp
David, the presidential retreat in Maryland.
 

United Flight 93 was en route from Newark, N.J., to San Francisco when it
crashed north of Somerset County airport, about 80 miles southeast of
Pittsburgh.  In Pennsylvania, an emergency dispatcher received a cell phone
call at 9:58 a.m. from a man who said he was a passenger locked in a
bathroom aboard United Flight 93, said dispatch supervisor Glenn Cramer in
neighboring Westmoreland County. The man repeatedly told officials the call
was not a hoax.
 

"We are being hijacked, we are being hijacked!" Cramer quoted the man from a
transcript of the call.  The man told dispatchers the plane "was going down.
He heard some sort of explosion and saw white smoke coming from the plane
and we lost contact with him," Cramer said.
 

FBI agent Wells Morrison wouldn't confirm that the plane was hijacked, but
said the FBI was reviewing the tape of the 911 call.
 

"At this point, we're not prepared to say it was an act of terrorism, though
it appears to be that," Morrison said. Rep. James Moran, D-Va., said after a
Marine Corps briefing in Washington that Flight 93 was apparently intended
for Camp David, the presidential retreat in the mountains of Maryland. The
crash site was 85 miles northwest of Camp David.
 

The 10 a.m. crash of Flight 93 occurred about 85 miles northwest of Camp
David near Thurmont, Md.
 

"There's a crater gorged in the earth, the plane is pretty much
disintegrated. There's nothing left but scorched trees," said Mark Stahl of
Somerset, who went to the scene.
 

He described the area as a former strip mine that is now a grassy field
edged by woods. The plane came down near the tree line, he said.
 

In Pennsylvania's Richland Township, police Chief Jim Mock said air traffic
control coordinators reported Tuesday morning that a large aircraft was
heading toward John Murtha Johnstown Cambria County Municipal Airport in the
township, about 60 miles east of Pittsburgh
 

The air traffic controllers said the aircraft would not identify itself,
according to Mock, who is also airport's emergency coordinator. Shortly
after talking to the controllers, Mock said, a plane crashed north of the
Somerset County airport about 20 miles away.
 

"It shook the whole station," said Bruce Grine, owner of Grine's Service
Center in Shanksville, about 21/2 miles from the crash. "Everybody ran
outside, and by that time the fire whistle was blowing."
 

After the crashes the three passenger terminals at Newark International
Airport were evacuated. At 11:30 a.m., several hundred people were still
clustered at the Terminal A baggage carousel, while shotgun-toting officers
patrolled. Ticket counters were deserted.
