(CNN) – New information reveals missing Malaysia Airlines Flight 370 was traveling in the opposite direction of its scheduled path for nearly an hour.
"If there was something so massive – failure of the airplane that caused the transponder to quit along with all the other communications – the crew actually could have thought returning to the airport they departed from was the best course of action," said retired commercial pilot John Ransom.
The plane, a Boeing 777-200ER, had stopped sending identifying transponder codes before it disappeared. But the aircraft has a number of redundant electrical systems on it.
"My first reaction would be somebody turned (the transponder) off, purposely turned it off," said former NTSB Board member John Goglia.
"A pilot would not do that, somebody that didn't want to be seen very well would do that," said Goglia.
