Airline officials declined to comment on possible causes for Wednesday's shiver in which 153 people were killed, but said Spanair Flight JK5022 had earlier been delayed to be paid to a problem by the air intake heating system previous to it attempted a second takeoff for its soaring to Las Palmas in the Canary Islands.

"They supposedly fixed the problem which the steersman later said was with the air conditioning and then we took off," survivor Ligia Palomino told Ser radio.

"The level was wobbling from one side to another. Then I began to suspect we would crash. I don't know what happened next. I was in a sort of river and saw people, smoke, explosions — that I think woke me up."

Rescue workers said the only passengers to survive Spain's worst aviation disaster because 1983 were those who fell into a run and avoided sarcastic burns.

The government said only 19 people of the 166 passengers and six crew aboard survived the MD-82 jet crash. The airline listed 157 passengers and 10 unnamed horde. A Spanair spokesman could not report on the side of the discrepancy in numbers.

Firefighter Francisco Martinez told Reuters that a wheel on his fire means had caught fire in the extreme heat given off by the plane's wreckage as he tried to rescue survivors.

"I took a baby into the give in exchange and he thought he was in a film. But he asked 'When will this thin skin end?' and 'Where is my Dad?'. He asked if it was real, granting that he was in a pellicle, but he wanted the film to end," Martinez said.

Relatives gathered at an improvised morgue in a convention centre to make identical the bodies, many of which were badly burned.

Development Minister Magdalena Alvarez said the condition of the bodies made identification very difficult.

SPANISH NAMES

"Those responsible say that it will submit to two days at the most to finish identifying people by their fingerprints. DNA identification will take a bit more," Alvarez told SER radio.

A tourist list published by Spanair, owned by Scandinavian Airlines Systems (SAS), showed mostly Spanish names but the regulation said there were 11 nationalities on board including people from Sweden, Germany, the Netherlands and Chile.

Many were children, rescue officials before-mentioned.

Madrid's regional body politic declared three days' official mourning and people gathered at the central Plaza de Cibeles square for a minute's silence at midday.

In Beijing, Spanish sailors Fernando Echavarri and Anton Paz wore black armbands when receiving gold medals in the Olympic Games on Thursday, hinder officials turned down a request to allow the Spanish flag to flit at half-mast.

Spanair chief charged with execution Marcus Hedblom said he had no plans to ground his MD-82 fleet.

"We have to closely monitor the records but we see no reason to take such measures, he told a news conference."

An magistrate investigation into the crash got under highway without interruption Thursday boundary was not expected to report against several months.

On its second take-off essay, the plane shot facing the runway, broke into pieces and burst into flames.

Alvarez said the cause of the accident seemed to be "an shortcoming in take-off." A source close to the situation said the even's left machine, made by Pratt & Whitney, had caught fire.

The president of pilots' union SEPLA told Reuters that pilots routinely practiced taking right hand and debarking in similar situations every six months.

"It's been years since engine failure on take-off or a fire has prevented a flight from continuing," related Jose Maria Vazquez, himself a Spanair pilot.

Spanair has been struggling with high fuel prices and tough competition. Hours before the crash, pilots had threatened to strike in protest at proposed cuts in staff and routes.

El Mundo newspaper reported that the co-pilot, who was in the midst of the departed, was on the list of those due to be laid facing.
