They seem to have found it, already.
They still have to narrow down the search to the actual plane, but I watched the news conference last night and I believe they’re now actually hearing the plane.
Just my opinion however. Could be wrong.
I was listening to the news this morning and I believe the Australians have identified the pinger on two scanning runs. They’re hoping for a third contact to triangulate more accurately but I think they’ve got it narrowed down to a three square mile area. Still a lot of territory to search to locate the recorders but better than before.
Sounds like you're very close to COMPLETELY discounting the "black hole" theory...
