ELT
I understand that the ELT is practically mute if it’s underwater.
If it is so, also because of this ugly episode (it's not the first), from which we must learn something, is it not possible to invent something that can transmit the emergency message and its location even after a ditching?
I think of a panel that breaks down when immersed in salt water and so allowing the expulsion and emersion of the device.
IMO
