(CNN) – Emotions have been swinging like a pendulum for those involved with the search for Malaysia Airlines Flight 370.
Just when it seems like they're close to finding out what happened to their loved ones, hopes are dashed by changing satellite data, or the cruel reality that what looked like plane debris was little more than ocean trash.
After more than a month of frustration and heartache, are the recent "pings" finally the breakthrough we've been waiting for?
CNN's Jake Tapper reports.
(CNN) – Time is of the essence for finding Malaysia Airlines Flight 370. The flight data and cockpit voice recorders' beacons appear to be sending pings, but the batteries are already past their expected expiration date.
CNN analyst David Soucie, author of "Why Planes Crash," sea operations and submersible expert Capt. Tim Taylor, and former Naval oceanographer Capt. Van Gurley discuss.
(CNN) – Two new pinger signals consistent with the missing plane's black boxes have been picked up by the Australian ship Ocean Shield. This is a major new lead in the search for Malaysia Airlines Flight 370.
The ship is towing a U.S. Navy pinger locator, and is the same ship that picked up two signals Saturday. All four of them are within a 17-mile area.
In about two weeks, the search area has gone from an overall search area the size of Alaska, to one the size of South Carolina.
But search crews say these new signals were weaker than the ones recorded on Saturday, the day the batteries on those data recorders' beacons were supposed to run out. It is now day 34 of the search, and time is clearly not an ally.
CNN's René Marsh has the latest developments.
(CNN) – Thanks to the detection of two new pings, the search area for Malaysia Airlines Flight 370 has narrowed. But searchers face daunting ocean depths, up to three miles down. Even with a potentially narrowed search area, there are still many unanswered questions.
CNN analysts Rob McCallum, an ocean search specialist, and David Soucie, author of "Why Planes Crash," and commercial pilot Anthony Roman discuss the latest challenges.
(CNN) – Pastor Dan Hertzler speaks about counseling students in the community after a mass stabbing at a Pennsylvania high school.
"In the midst of this evilness, God is still good," says Hertzler.
