Me too. I mean, on one hand I think they appear to have been more effective at staying on line and in control than paddles would have been.
On the other, I'd be araid of being impaled by one. I mean, some sort of impact had to bend that one oar, right? Did you see that thing?
Probably the more "Officialy Clean" runs of this modern era, since both katak descents ended out of control with either blown skirt or broken paddle. At least one of those creature crafts appeared to "Clean It". Noteworthy.
