There's pleasure to be had tugging, apparently...
Umm.. the Fun was had mainly when not flying the Tug!
Heard from a reliable source that there was a bit of a coming together between two ASG 29's (?) a few days ago. Thankfully no-one was injured and both Gliders landed ok.
Haven't flown Gliders in many years bit I suspect that FLARM would be more of a nuisance when Gaggle flying. I remember once in a Regional Competition (way back in the mid 70's) sharing a thermal with about 15 Gliders, with the highest a/c being about 1,000' above the lowest in the gaggle.
I was about half way up, and clearly remember not looking at the instrument panel once whilst in that gaggle.
