Some years back there was an article (maybe several?) in SOARING magazine
about installing tip strobes on gliders ...

Anyone remember/know what issue(s) that was in? I'm researching collision
avoidance stuff (again, still . . gr)

(Boy, do I wish there was a good INDEX to Soaring! I've got every copy
since 1966 and a few going back to 1937, making a fantastic resource that's
darn near unusuable because there are no complete indices (and the few that
were printed back in the seventies and eighties are poorly organized . . .))
