ELT - I think that’s what I read. Is the ELT contained within the ‘Black Box’ data recorder? (In the tail of the plane?)

When Sully landed in the Hudson, did the ELT transmit? Although they don’t have 20+ foot swells to deal with in the Hudson, and the plane stayed intact.

Just saw a graphic that shows the number of aircraft and ships searching the southern corridor(west of Australia) along with their country of origin.

Total of 12 countries searching, 25 aircraft, 6 helicopters, 20 ships. Yet the U.S. has only 1 aircraft and 0 ships contributing to the search in the Southern Corridor. Seems odd to me. Who knows.

The ELT(Emergency Locator Transmitter) and the black box are different. Small planes like Cessna 172s won't have a black box. I'm not sure what the rules are anymore on ELTs, but small aircraft do have them. I think most, if not all, are in the tail.

I do not know if the ELT went off on Sully's flight, that would be interesting to know.
