Thanks for all these replies.

Below is a message I got from Swiss FLARM today:

==========================================
'Unfortunately it is impossible to do a correct (and
honest) statistic since there are simply too little
datapoints.

However, we can say that to the best of our knowledge
there have been no collisions with fatal outcomes between
Flarm equipped aircraft or between Flarm equipped aircraft
and obstacles. But, there have been multiple collisions
with fatalities this summer (French Alps) between aircraft
that did not carry Flarm.

Currently more than 5000 Flarm devices are in use worldwide.
No pilot has ever returned a (non defective) device
because he was not satisfied with it.

We are in the process of getting to know the UK situation,
but expect to become more visible and vocal within
days/weeks.'
==========================================

If, as we are told, only 10% of the gliders in the
Alps are FLARM free and they have had all the mid-air
fatalities then it is quite a significant finding,
albeit short term.

It was interesting to read on the board about the collision
in a thermal between two Swiss FLARM equipped gliders
who already knew of each other's presence. It just
goes to show that no matter whether a glider is spotted
by eyeball or FLARM you still have to avoid it. I
presume that was not a fatality.

I think that European clubs are fitting FLARMS in the
tugs because it is mentioned in some off-board messages
I have received. Apparently early on it gave false
alarms on tow but that this now has been addressed
in the updates.

Thanks,
