SAN DIEGO - New questions are being raised about why a missing Malaysia Airlines jet was in the air for so long before it deliberately went off course. Investigators do not know why it continued flying for more than six hours after severing contact with the ground.
Local aviation and security expert Glen Winn offers some possibilities of what could have happened.
"Maybe there was a resistance that took place from members of the cockpit or maybe it was a Flight 93 resistance where all the passengers stood up and said, 'No, this isn't going to happen' and there was a battle that took place on the airplane," said Winn.
On Saturday, the search entered a new phase after Malaysia's leader announced that someone in the cockpit purposely took the aircraft off course.
Winn believes search crews have a very good chance of finding the missing plane, even if it is in the deepest part of the ocean.
"We have deep reaching radars and so on and of course sonar, which has improved itself by leaps and bounds, so I would say the potential is 90 percent," he said.
Investigators are looking into all possibilities as to why the Boeing 777 deviated so drastically from its path.
With no evidence of a crash or any type of landing, Winn says authorities will indefinitely rely on information from the plane's black box if it is still intact when the plane is found.
"Something with this aircraft … it will come about when they find it with the black boxes, the direction it was going and perhaps overhearing conversations that can be taken from the tapes," said Winn.
The search now includes 43 ships and 58 aircraft from 14 different countries, including the San Diego-based USS Kidd.
