IMHO the Scottish incident is a good example of one accident that would
have benefitted from an ELT - the glider was mostly intact and the
pilot injured but incapacitated.

While I'm also agreeing they should not be not compulsory for all
gliders - training ships and twirlybirds don't need them - an ELT would
be a wise investment for pilots flying alone over inhospitable terrain.

Also filing a flight plan would not be a bad idea for flights like
this. I wonder why more glider pilots don't do this - it doesn't cost
anything!
