According to Chinese News Paper, one reporter first reported by satellite phone that three people on a boat deployed by the Haixun 01 Rescue Ship detected pings of 37.5KH for a short time on 4/3 at about 16:34 local time . Each of them verified they heard the pings. The first one claimed he heard at least 200 pings for about 3 minutes before he told his companions he heard the sound and two others verified the pings. And then one of them changed the position of the detecting head (which they called Energy Transformer attached to a 2m long pole into the water), then they lost it. They said it was so sudden they didn't think and prepare to record the pings and it didn't mention how long the pings lasted (now they said it lasted more than 10 minutes). At about 15:57 4/5 local time, it detected another pings lasted about one and half minute, and they still try to verify this one.
Question is: are these pings came from the MH370 black box? And why these pings only lasted such a short time when detected? Is it because the signals were weak and in and out? Anyway, this is first good news for so long time.
The technicians who heard the pings compared with the ping sample from Boeing Company and confirmed the sound characteristics are the same.
By the way, the reporter confirmed this team had experience of locating of black box from a downed helicopter in The Yangtze River of China and retrieved it in 2005.
They think the average depths of the bottom of the sea at that area they heard the pings this time is about 5000M and that is about of limit of the black box pings can reach and that explains why a little angle change would lost the signals and they must be at almost vertical point to the box---great news. The only other explanation is some one dropped a "pinger" to direct search before--but do the pinger dropped by searching planes got the same frequencies as the black box? I really doubt
