Part of the ELT survival problem is the antenna. Most (maybe all)
of the ELT antennas on modern aircraft are external, and tend to
get ripped off during the crash. As a result, even though the
transmitter may survive the impact, nobody can hear the signal.
I understand that the FAA is considering ELT's with integral
antennas to increase the survivability of the ELT.

As an aside, how many people actually check to see if their
ELT is transmitting after they land. I suspect it isn't a high
percentage (I know I don't do it regularly).
