Brian Drake donned a wingsuit atop the ENSA ski-run in Couloir, France, and then did a ground-skimming trench-run that left me half-terrified, half-tingling in sympathy. Wish they'd shown the landing, though.
Trench-run in a wingsuit
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
