Is it wreckage from Flight 370? Has the missing plane finally been found at long last?
It was 11:26 p.m. Eastern Time last night when the bombshell announcement came from Prime Minister Tony Abbott before the Australian parliament.
Abbott announced, "New and incredible information has come to light in regards to the search for Mayalasia Airlines Flight 370 in the South Indian Ocean."
The Australian government has released satellite photos of two large pieces of possible debris from the jetliner. The debris was photographed over the southern Indian Ocean, 1,500 miles from the city of Perth.
John Young, emergency response manager for the Australian Maritime Safety Authority, said at a press conference, "This is a lead. It is probably the best lead we have right now."
One piece of debris is 16 feet long. The other larger piece is 79 feet long, and experts say it could be part of the plane's tail section.
Former NASA satellite expert Ken Christensen told INSIDE EDITION, "It does look like debris. If it's from an aircraft, I think it's too early to tell until people actually physically see it."
If the debris is indeed from Flight 370, it could have floated hundreds of miles from where the jet actually crashed.
The location of the debris is on a straight line due South from the last known location of the jetliner.
On the Today show, aviation expert Robert Hager said, "Where it is, it would indicate it flew to the end of its range of fuel and it went in because it ran out of fuel."
Now, there's new speculation that Flight 370 was a "zombie" plane, with everyone on board, including the pilot and co-pilot dead as it flew to its doom.
Former CIA analyst Robert Baer still believes the plane was hijacked.
"The question is motivation. And I think the simplest explanation is someone went nuts on that plane," said Baer.
The remote part of the Indian Ocean where the debris was spotted could be as much as three miles deep.
Chris Curl from the Scripps Institute of Oceanography told INSIDE EDITION, "In that area, with the sea conditions that they're going to encounter, to find something of that size would be miraculous."
Robot submarines may be used to search for the plane's black box. Only then will we learn the truth behind aviation's greatest mystery.
