(CNN) – Officials are tightening the search zone for Malaysia Airlines Flight 370 to the smallest area yet, just about 18,0000 square miles, far narrower than the day before.
We are now on the 35th day since Flight 370 vanished with 239 people on-board.
As many as 15 planes and 13 ships are taking part in the search zone, after a possible signal was once again discovered in the water, for a fifth time.
The team came by this latest potential break in the mystery, using very different – and maybe more efficient – technology.
