Sand Wasps are at least mostly French, and very much alive. Arnox is still very active and flies with other members of his group.
As for Rεd ZΦmbiε (salute to anybody who understands what's wrong with the way I wrote that), I haven't seen them around, but who knows.
Squash is definitely right about the Dutchmen thing. And saying that The Flying Dutchmen are dead because they compete as The Whalers would be like saying that the Ducks are dead because we compete as the Paddling, Raft and Brood. So they're definitely (doing science and) still alive.
