CAPE CANAVERAL, Fla. — Space Shuttle Columbia apparently blew up and disintegrated in flames over Texas Saturday morning, just 16 minutes before it was expected to land at Cape Canaveral.
Seven astronauts -- six Americans and the first Israeli to go into space -- were aboard the shuttle, which had been orbiting the Earth for 16 days.
President Bush was alerted to the possible disaster. The White House said there was no indication that terrorism was involved.
NASA lowered its flags at 11 a.m. EST.
Television footage showed a bright light followed by smoke plumes streaking diagonally through the sky. Debris appeared to break off into separate balls of light as it continued downward.
Columbia was at an altitude of 207,000 feet over north-central Texas at a 9 a.m., traveling at 12,500 mph, when Mission Control lost all contact and tracking data.
The space shuttle had been aiming for a Florida landing at 9:16 a.m.
Search and rescue teams were fanning out throughout the Dallas-Fort Worth area, searching for debris. Residents were warned not to pick up any fallen debris, which was described as potentially dangerous.
There were reports of debris being found in north central Texas.
Several residents reported hearing "a big bang" at about 9 a.m., the same time all radio and data communication with the shuttle and its crew was lost.
Just over an hour after the shuttle had been expected to land, officials at Kennedy Space Center announced over loudspeakers that a statement on the fate of the shuttle would be issued shortly.
It was the 113th flight in the shuttle program's 22 years and the 28th flight for Columbia, NASA oldest shuttle.
Inside Mission Control, flight controllers hovered in front of their computers, staring at the screens after contact was lost. The wives, husbands and children of the astronauts who had been waiting at the landing strip were gathered together by NASA and taken to a secluded place.
"A contingency for the space shuttle has been declared," Mission Control somberly repeated over and over as no word or any data came from Columbia.
In 42 years of U.S. human space flight, there had never been an accident during the descent or landing phase of a mission. On Jan. 28, 1986, space shuttle Challenger exploded shortly after liftoff.
Shortly after Columbia lifted off Jan. 16, a piece of insulating foam on its external fuel tank came off and was believed to have hit the left wing of the shuttle. Leroy Cain, the lead flight director in Mission Control, assured reporters Friday that engineers had concluded that any damage to the wing was considered minor and posed no safety hazard.
Gary Hunziker in Plano said he saw the shuttle flying overhead. "I could see two bright objects flying off each side of it," he said. "I just assumed they were chase jets."
"The barn started shaking and we ran out and started looking around," said Benjamin Laster of Kemp, Texas. "I saw a puff of vapor and smoke and saw big chunk of material fall."
Security had been extraordinarily tight for Columbia's 16-day scientific research mission because of the presence of Ilan Ramon, the first Israeli astronaut.
Ramon, 48, a colonel in Israel's air force and former fighter pilot, had survived two wars. He became the first man from his country to fly in space, and his presence resulted in an increase in security, not only for Columbia's launch, but also for its planned landing. Space agency officials feared his presence might make the shuttle more of a terrorist target.
A senior U.S. official, speaking on condition of anonymity, said Saturday there was no threat made against the flight and that the shuttle was out of range of a surface-to-air missile.
"The government of Israel and the people of Israel are praying together with the entire world for the safety of the astronauts on the shuttle Columbia," Prime Minister Ariel Sharon's office said in a statement.
Columbia's crew had completed 80-plus scientific research experiments during their time in orbit.
Only two of the seven astronauts had flown in space before, the shuttle's commander, Rick Husband, and Kalpana Chawla. The other five were rookies: pilot William McCool and Michael Anderson, David Brown, Laurel Clark and Ramon.
Just in the past week, NASA observed the anniversary of its only two other space tragedies, the Challenger explosion, which killed all seven astronauts on board, and the Apollo spacecraft fire that killed three on Jan. 27, 1967.
