All of this talk of tracking and ejectable recorders seems to me to be waste of time and money.
Failure to recover the recorders is extremely rare, MH370 is a one-off event.
Exactly. A better ELT however (intended to save survivors) would be much more important than a device which allows to publish the report a few days earlier. In which major large aircraft accident of the last 50 years has the ELT been of any help to the survivors?
If the ELT points you to the crash site, finding the recorders will typically be a piece of cake.
