Exactly guys...
Some of us are pilots and boaters... I just went over 2000 miles on my vessel with Epirb equipment that was relatively inexpensive and could pin-point my location anywhere in the world. While I'm not trying to compare the two exactly, I think you get my point.
I know the equip. they put on commercial aircraft are designed to withstand catastrophic accidents. So, the question remains why they seem to be saying they are looking for a needle in a haystack. If they are, changes need to be made....
