Being the biggest and most detailed, that first pic is obviously noteworthy. But its the second, delta shaped object that really gets my attention.

That's the shape that's being relentlessly imitated to this day.

With the first pic, it sometimes seems like whatever they are, show us something that looks familiar, something sort of in line with the times, like this big, unwieldy cigar thing, reminiscent of a submarine.
