Kuala Lumpur, Malaysia (CNN) -- Australian authorities have spotted two objects in the southern Indian Ocean that are may be debris from the missing Malaysia Airlines Flight 370.
The objects are indistinct but of "reasonable size" -- the largest about 24 meters long (79 feet), said John Young, general manager of emergency response for the Australian Maritime Safety Authority. They were "probably awash with water and bobbing up and down," he said.
"If that piece of the plane is that big, maybe it's the tail section" David Gallo, who co-led the search for Air France Flight 447 which crashed in 2009 in the Indian Ocean and remained out of sight for two years. The tail height of a Boeing 777 is 60 feet.
The announcement raises hopes of finding parts of the plane after a huge search that is now in its 13th day. Previous reports of debris found in the sea have not turned out to be related to the passenger jet, which vanished over Southeast Asia on March 8.
Australian Prime Minister Tony Abbott first announced the discovery to the House of Representatives in Canberra on Thursday.
Australian search teams have been at the forefront of the hunt for the missing plane in the remote southern Indian Ocean.
"There have been so many false leads and so many starts and changes and then backtracking in the investigation," Mary Schiavo, a CNN aviation analyst and former inspector general for the U.S. Department of Transportation, said. "He wouldn't have come forward and said if they weren't fairly certain."
At the Lido Hotel in Beijing where family members of some of the passengers on the missing plane have waited for news for days, relatives gathered around a large screen television watching the Australian news conference. They leaned forward in their chairs, hanging on every word. Some sighed loudly.
Malaysia Airlines said it won't be sending representatives or family members to Perth until the objects are confirmed as plane debris.
'The best lead we have right now'
The images of the objects were captured by satellite and were being assessed by the Australian Geospatial-Intelligence Organisation. The images were taken near the area that has been scoured by search teams in recent days.
Although the search area spans nearly 3 million square miles, a U.S. government official familiar with the investigation said the missing plane is most likely somewhere in the southern Indian Ocean.
"This is an area out of normal shipping lanes, out of any commercial flight patterns, with few fishing boats, and there are no islands," the official said.
Young cautioned the images may not be from the plane. There can be other debris out there, from ships, for example.
The objects were seen in the heart of what is known as the Indian Ocean Gyre. There is little to no oceanic current movement in the region and the area is notorious for trapping debris. It's one of the five major gyres in the world's oceans and is known to contain a "garbage patch."
"It is probably the best lead we have right now," Young said. "But we need to get there, find them, see them, assess them to know whether it's really meaningful or not."
The visibility in the area is poor, Young cautioned. "The weather is not playing the game with us," he said.
Planes arrive
A Royal Australian Air Force Orion aircraft has already arrived in the area, Young said, and three other planes are being sent there, including a New Zealand Air Force Orion and U.S. Navy P8 Poseidon.
An Australian C-130 Hercules plane has been tasked by Australian authorities to drop market buoys in the area, he said.
"The first thing they need to do is put eyes on the debris from one of the aircraft," said aviation expert Bill Waddock. The buoys will mark the place and transmit location data.
The Malaysian Navy has six navy ships with three helicopters heading to the southern Indian Ocean to take part in the search, a Malaysian government source said.
'Every lead is hope'
"Verification might take some time. It is very far and it will take some time to locate and verify the objects," the Malaysian government source said.
Malaysia's Acting Transportation Secretary Hishammuddin Hussein told CNN he couldn't disclose the information the Australians shared with Malaysia. He said he hadn't seen the images.
But he added, "Air and vessels are going there. You know how big the area is. Every lead is hope. We have been consistent with our process and we want to verify properly."
Flight simulator probed
Other pieces of information related to the investigation into the plane's disappearance had emerged Wednesday.
Investigators looking at the flight simulator taken from the home of Capt. Zaharie Ahmad Shah, the pilot of the plane, have discovered that some data had been deleted from it, Hishammuddin said at a news conference.
What the revelation means is unclear. It could be another dead end in an investigation that has been full of them so far, or it could provide further evidence for the theory that one or more of the flight crew may have been involved in the plane's disappearance 12 days ago.
"It may not tell us anything. It's a step in the process," one U.S. law enforcement source told CNN. "It could be a very insignificant detail in the process."
Investigators have been looking into the background of all 239 passengers and crew members aboard the plane that vanished in the early morning hours of March 8 while en route from the Malaysian capital of Kuala Lumpur to Beijing.
Particular attention has focused on the pilot and first officer, but authorities have yet to come up with any evidence explaining why either of them would have taken the jetliner off course.
Hishammuddin didn't say what had been deleted, but simulation programs can store data from previous sessions for later playback. He also did not say who might have deleted the data.
FBI examination
Specialists are examining the simulator in hopes of recovering the data that was deleted, Hishammuddin said.
Among them are experts at the FBI's forensics lab in Quantico, Virginia, who are examining a copy of the simulator's hard drive, as well as a copy of the hard drive from the computer of co-pilot Fariq Ab Hamid, law enforcement sources told CNN.
The FBI examination of the computer drives involves sorting through a large volume of data, according to a senior U.S. official with knowledge of the investigation.
"It is going to take some period of time, but we are analyzing it with a great degree of urgency. It is prioritized right at the top because the world is trying to figure this out," the official said on condition of anonymity.
Deleted files from Shah's simulator could reveal it had been used to practice diverting the plane and flying it to an unfamiliar airport, experts said. But even if investigators retrieve past simulations showing that Zaharie practiced flying to seemingly odd locations, that doesn't necessarily indicate evidence of anything nefarious, said Mary Schiavo, a CNN aviation analyst and former inspector general for the U.S. Department of Transportation.
"You put in strange airports and try to land there, just to see if you can do it," said Schiavo, adding that she sometimes does just that on the flight simulation program on her home computer.
'Grasping at straws'
President Barack Obama called the search for Flight 370 "a top priority," telling KDFW of Dallas on Wednesday that the United States will keep working on it.
"We have put every resource that we have available at the disposal of the search process," he said.
But beyond help with the computer drives, the Malaysian government has not put in a formal request for additional FBI help overseas, according to the senior U.S. official.
"We have made it clear we are ready to provide help whenever they need it," the official said. "We are grasping at straws. No one is running on anything white hot."
More than 60 ships and 50 aircraft are participating in the search. But at least two aircraft, a Japanese search plane and a U.S. Navy P-3 Orion, sat on a runway at a Subang air base this week after Indonesia refused to allow the planes to fly through its airspace.
"From what I understand, this is an international operation," Cmdr. William Marks, spokesman for the U.S. Navy's 7th Fleet, told CNN by telephone. "I'm confident we're going to be flying today or very soon."
Later, Indonesia's military spokesman told CNN clearance was given to all search planes.
Angry families want answers
The lack of progress has angered and frustrated families, who have accused Malaysian officials of withholding information.
Some family members staged a protest at the Kuala Lumpur hotel where media covering the search are staying. Their efforts were cut short by security guards who removed them through a crush of reporters, dragging one as she screamed.
"I don't care what your government does," one woman shouted, referring to the Malaysians. "I just want my son back."
The agony of the wait is also being felt by families in Beijing, the scheduled destination for Flight 370. They gather daily for a briefing with officials.
Ye Lun, whose brother-in-law is on the missing plane, says every day is the same. He and his group leave the hotel in the morning for a daily briefing, and that's it. They go back to the hotel to watch the news on television.
In a statement, Hishammuddin said Malaysian authorities "regret the scenes at this afternoon's press conference."
"One can only imagine the anguish they are going through," he said of the families. "Malaysia is doing everything in its power to find MH370 and hopefully bring some degree of closure for those whose family members are missing."
An abrupt change in direction
The disappearance continues to intrigue the public and frustrate officials, who have turned up no sign of the plane despite the involvement of teams from 26 nations.
On Tuesday, a law enforcement official told CNN that the aircraft's first major change of course -- an abrupt westward turn that took the plane off its route to China and back across the Malay Peninsula -- was almost certainly programmed by somebody in the cockpit.
The change was entered into the plane's system at least 12 minutes before a person in the cockpit, believed to be the co-pilot, signed off to air traffic controllers. Two minutes after the signoff, the plane's transponder stopped communicating details about the plane's altitude, speed and heading.
Some experts said the change in direction could have been part of an alternate flight plan programmed in advance in case of emergency; others suggested it could show something more nefarious was afoot.
But Hishammuddin said Wednesday that "there is no additional waypoint on MH370's documented flight plan, which depicts normal routing all the way to Beijing."
The Thai military, meanwhile, said it had spotted the plane turning west toward the Strait of Malacca early on March 8. That supports the analysis of Malaysian military radar that has the plane flying out over the Strait of Malacca and into the Indian Ocean.
But it didn't make it any clearer where the plane went next. Authorities say information from satellites suggests the plane kept flying for about six hours after it was last detected by Malaysian military radar.
Malaysian authorities, who are coordinating the search, say the available evidence suggests the missing plane flew off course in a deliberate act by someone who knew what they were doing.
