Barber's "8gon" shape

I'm a bit confused by Barber's description of the "8gon" recovered craft and this made up word... He said it's a "disc" and is divided into 8 sections when viewed from above.

So is the craft circular when viewed from above and has 8 sections delineated by seams or something? If that's the case calling it an 8gon is weird because it sounds somehow angular like every other "gon" in geometry...

Or is it octagonal when viewed from above? In which case can't we just call it an "octagon"?!
