That would be the imaginatively named 'Light Craft'.
Discovery occasionally shows it on various documentaries (at least it
does in the UK).
Bye for now,

You all might be distorting your memories some. It had a water drop
splashing in water shape as I recall, minus the most extended droplet part
that is. So I guess you could say it was both saucer and toy top shaped.

My "pie-pan" description came from what the author of the article I read
said it looked like. It might easily have looked like a toy top, but the
author described it as a pie pan shape. The only picture I can remember
is a white circular flat thing in the air, not a detailed photograph.
Can't we find something better to argue about? :-)

That seems to be what I remember. I can see why it was described as a
top, I think the "pie pan" version was a different design.
