A newspaper is reporting that the voice recorder indicates that one of the pilots was locked out of the cockpit before a Germanwings jetliner plummeted into a remote Alpine mountainside.
The New York Times is citing an investigator it doesn't identify as saying that the audio shows that after an ordinary start to the flight, one of the pilots left the cockpit and could not get back in.
The investigator told the newspaper that the pilot began knocking quietly on the door, then became more insistent, saying that eventually: "You can hear he is trying to smash the door down."
The investigator does not speculate as to why the other pilot didn't open the door or make contact with ground control before the plane crashed Tuesday. All 150 people aboard were killed.

A bus with 14 relatives of the Spanish victims who died in the French Alps plane crash has left Barcelona for an overnight journey that will take them to the crash area by Thursday.
Those going on the bus apparently did not want to take a Thursday morning flight from Barcelona to Marseille that is expected to shuttle many more relatives toward the site.
Spanish civil protection spokesman Sergio Delgado said all of the Spanish relatives will meet up in Marseille and head to the remote crash zone in Seyne-Les-Alpes together.
Spain's government has said at least 51 Spaniards were among the 150 victims of the crash. Airline Germanwings has said 35 of the 125 passengers identified were Spaniards.

Lufthansa CEO Carsten Spohr says the late take-off from Barcelona of the Germanwings plane that crashed in the French Alps was due to airport congestion and not related to the incident.
Spohr added the crash of the plane that killed 150 people remained "incomprehensible."
Spohr said Wednesday that "we still cannot understand" what happened in the "terrible accident." He said it is "too early for speculation" about the cause.
The aircraft "had a clean maintenance bill" from an inspection the day before Tuesday's crash and was "in perfect technical shape," he said. No distress signal was received from the plane.
Spohr said he had a "very, very emotional meeting" with the relatives of the victims.
Lufthansa, which owns Germanwings, has offered "immediate financial help" for those who need it.

The northeastern Spanish town of La Llagosta said two of the 150 crash victims were natives of the town, one of them a woman who had got married in the town on Saturday and was moving to Duesseldorf with her Moroccan husband, also a crash victim.
In a statement on its website, La Llagosta town hall named the woman as Asmae Ouahhoud el Allaoui, 23. The husband's name wasn't made available.
The town hall said another man born there, Francisco Javier Gonalons, 42, also died in the crash.

The director of France's aviation investigative agency says there currently is not the "slightest explanation" for what caused the Germanwings plane to lose altitude and crash in the Alps.
Remi Jouty says the investigation could take weeks or even months.
Jouty says the plane was flying "until the end" — slamming into the mountain, not breaking up in the air.
He says the final communication from the plane was a routine message about permission to continue on its route.
5:25 p.m. (1625 GMT, 12:25 p.m. EDT)
The director of France's aviation investigative agency says audio has been recovered from the cockpit recorder salvaged from the crash of the Germanwings plane in the Alps.
Remi Jouty says the material includes sound and voices, and was extracted Wednesday afternoon from the mangled black box recovered from a mountainside.
Jouty says it was too early to draw conclusions from the recording. The case of the second black box, the flight data recorder, has been found, but not its contents, French President Francois Hollande said minutes earlier.
Jouty says he couldn't confirm that the case of the second black box had been recovered.

Investigators will use the cockpit voice and flight data recorders to map out and focus their work, says Alan E. Diehl, a former air safety investigator.
"Both will point you in directions of what is critical," Diehl says. "Based on what you learn from the recorders, you might focus on key pieces of wreckage."
The four possible causes of any crash are human error, mechanical problems, weather, criminal activity or a combination of two or more. Diehl says investigators will work backward, starting by eliminating what didn't happen.

France's aviation investigation bureau has released photos of the badly mangled voice data recorder from the Germanwings flight that crashed into an Alpine mountainside.

The cockpit voice recorder was recovered on Tuesday, and French officials say they are working to pull its data.

Germanwings' chief executive says the airline's current information is that 72 Germans, 35 Spanish citizens and two Americans were on board the flight that crashed in southern France.
Thomas Winkelmann told reporters in Cologne on Wednesday that the list isn't yet final because the company is still trying to contact relatives of 27 victims.
There were two victims each from Australia, Argentina, Iran and Venezuela. One victim each came from Britain, the Netherlands, Colombia, Mexico, Japan, Denmark, Belgium and Israel.
Winkelmann says in some cases victims' nationality isn't entirely clear, in part because of dual citizenship.

Interior Minister Thomas de Maiziere told reporters in Berlin on Wednesday that "according to the latest information there is no hard evidence that the crash was intentionally brought about by third parties."

The principal of the German high school where 16 students and two teachers died in the Germanwings crash says "nothing will be the way it was at our school anymore."
Ulrich Wessel, principal of the Joseph Koenig High School, said Wednesday that when the first call came about the crash, he hoped that the students had missed the plane.
But the regional governor informed local officials that they were on the passenger list.
Wessel says one of the teachers who was on the plane had been married for less than six months.
He said: "It is a tragedy that makes one speechless and we will have to learn to deal with it."

The mayor of a town close to the site of the plane crash in the French Alps that killed 150 says bereaved families are expected to begin arriving in the town Wednesday morning.
Francis Hermitte, mayor of Seyne-Les-Alpes, says said local families are offering to host the families because of a shortage of rooms to rent. Leaders of France, Germany and Spain will also meet with them in a makeshift chapel set up in a gymnasium, Hermitte said.
Marion Cotterill, head of civil protection there, says the priority is to welcome families humanely. "We offer a hot drink, a smile, a warm regard, or psychological counseling if asked for."
Interior Ministry spokesman Paul-Henry Brandet says overnight rain and snow in the crash zone has made the rocky ravine slippery, increasing the difficulty of reaching the steep and remote area.

An Israeli citizen who lived in Spain was among the victims of the French plane crash, the Israeli Foreign Ministry said Wednesday.

Although officials have been firm that no cause has been ruled out, Cazeneuve said terrorism is not considered likely.
Segolene Royal, another top French official, says the seconds between 10:30 a.m. and 10:31 a.m. are considered vital to the investigation into the crash. She says the pilot stopped responding after 10:31.

Helicopter operations have resumed over mountainsides in the French Alps where a German jetliner crashed, killing all 150 people on board.
Under overcast skies, with temperatures just above freezing, helicopters resumed flights Wednesday over a widely scattered debris field.
A black box has been recovered from the scene. The Airbus A320 operated by Germanwings, a budget subsidiary of Lufthansa, was less than an hour from landing in Duesseldorf on a flight from Barcelona Tuesday when it unexpectedly went into a rapid descent. The pilots did not send out a distress call and had lost radio contact with their control center, France's aviation authority said.
