guess what? there is a new theory about where the wreckage of malaysia flight 370 really is right now. if this theory is correct, researchers have been looking in the wrong place the entire time. a group of outside experts say that fresh analysis of raw satellite data actually points to an unsearched area just south of where those pings were detected. could this be the answer to the big mystery? here s cnn aviation correspondent renee marsh. reporter: right ocean, right arc, but wrong spot. a group of independent experts say they believe flight 370 went down here, hundreds of miles southwest of where crews spent weeks searching. my personal opinion is that we re at the 80% to 90% confidence level. michael exner and other experts pushed for the release of raw satellite data which government officials used to calculate the kleen s possible final resting place. now that they have it, they
on the inmarsat data, david. what does that mean, how is that going to change the search effort going forward and how much confidence do you have in the location where even though it s some 23 plus thousand square miles that they re going to be searching that it s going to be there? well, i think that it is somewhere in that 23,000 square miles. but because i have some confidence in that inmarsat data after looking at what they released and talking with other professionals. why do you have confidence in inmarsat data? what s different in the inmarsat data and the data that was brought in that detected the pings? how is that different? the inmarsat data that detected the handshakes? yes. is that what you re referring to? i worked with michael exner to find out what that meant. even at that, even if we took in those considered those variables that we had that we don t know now, it still puts it in that very same area.
for a leading country to put out there. reporter: the search for the plane has been focused along the final arc but there is a margin of error. it could be off by six miles either way. plus, the plane could have glided for 23 miles in either direction. put together, that s a margin of error nearly 60 miles wide. this data proves impossible for some of the wilder theories of where the plane might be, like the notion it landed at a u.s. military base in the indian ocean. satellite expert michael exner says it s clear the plane went down near the final arc. it had to be on that arc. i think the inmarsat data is very accurate in that regard. we knew that before and this data released today just reinforces that conclusion. it did not go to diego garcia. reporter: but some families are not sure just yet.
