Investigators are hunting for clues into Monday's plane crash in Indonesia which killed at least 147 people, among them 47 who were on the ground.
The plane's flight data recorder has been found
The Mandala Airlines Boeing 737-200 crashed shortly after taking off from Medan. At least 14 passengers survived.
President Susilo Bambang Yudhoyono, who visited the crash site on the island of Sumatra, ordered an inquiry.
Transport Minister Hatta Rajasa said investigators would look into why the plane failed to take off properly.
He said it would be several weeks before the cause of the crash was known, the Associated Press reports.
Officials say the plane's flight data recorder has been found.
People have been looking for loved ones among bodies in a hospital morgue.
"I found my son-in-law because I remembered the trousers he was wearing," Asiyah said.
"But I cannot find my daughter. I will stay here until I do."
One man, Haji Muhammad Ersani visited his daughter, Fritina, who escaped from the plane with her 18-month-old boy Ridatul.
"She only remembers that when the plane went down and split apart, she immediately got out and watched as her eldest son was on fire," he said, quoted by AP.
"She hasn't said much. She's still in shock."
The crash happened during overcast conditions.
The plane plunged onto a busy road in a residential area near the city's airport. Fire engulfed the wreckage and dozens of homes and cars were destroyed by the impact.
A Mandala spokesman told AFP news agency that there were "no signs of terrorism".
Mandala is largely owned by Indonesia's military, and has been forced to cut costs in recent years to stave off losses.
The plane entered service in 1981, but was not due to be retired until 2016, and received a full service in June this year.
