Head of company that manufactured black box pingers says initial ping data "looked very promising"

Anish Patel of Dukane Seacom, the company that manufactures the pingers aboard Flight 370, tells CNN the pings detected by the Ocean Shield were actually at 33.3 mHz – a lower frequency than the standard locator beacon frequency of 37.5 mHz.

Mr. Patel joined CNN aviation analyst Miles O'Brien and Richard Quest of "Quest Means Business" to explain why the detected pings might have a lower frequency.

    ERIN...ERIN...ERIN: Please look into the people saying they can track their IPhones anywhere in the world. IF THAT IS TRUE, then why can't ANYBODY track the passengers phones?????

    Q: Why don't pingers and black boxes have some type of buoy in case of water crashes? Seems simple enough and would increase chance of locating.

    Has anyone thought about the possibility of a piece of the tail section, along with the recorders being semi-buoyant and moving around. They picked up the signals several hundred miles from where the Chinese originally found it. There could be pieces of this plane moving around on the underwater currents.
