I can't directly answer this question but very nearly had one myself this
summer.

Was flying near Col de Carro in French Alps. Ground there is about 3-
3200 metres, Cloudbase I recall being around 3800 so not a huge
amount of room. There were alot of gliders in the area, I could see at
least 7/8. Three were below and in front of me in a thermal and I
planned to pass above their thermal. Flarm was giving me collision
warnings and I (WRONGLY!) assumed it was the gliders in front of me.

I then saw another glider at 90 degrees to my track heading straight for
my wing tip at exactly the same level. They were horribly close and I do
not know how we did not collide.

The experience has reinforced something said to me, as a a student
many many years ago, pre Flarm but just as relevant ' Don't
concentrate on the gliders you have seen. You're not likely to collide
with them. Keep looking for the ones you haven't seen.' (Thanks Mike
