KUALA LUMPUR, Malaysia — Close to three months after the Malaysian jetliner disappeared, the government on Tuesday released reams of raw satellite data it used to determine that the flight ended in the southern Indian Ocean, a step long demanded by the families of some of the passengers on board. But while the 45 pages of information may help satisfy a desire for more transparency in a much criticized investigation, experts say it's unlikely to solve the mystery of Flight 370 — or give much comfort to relatives stuck between grieving and the faintest hope, no matter how unlikely, their loved ones might still be alive. "It's a whole lot of stuff that is not very important to know," said Michael Exner, a satellite engineer who has been independently researching the calculations.
