Do Balrogs Have Wings?

[Mister Underhill]

The math and biology of these things doesn't come into question, however, since reasonable assumptions can be made about them without creating conflicts.

I guess my point is that you can't make a convincing argument that the Balrog couldn't enter such and such a room when you don't know:

• Anything about the Balrog's anatomy except that he's in shouting distance of man-height (and has wings ).
• The size of the door.
• The size of the room.

You can make stuff up until the cows come home, but the only thing we know for sure is that the bridge span across the chasm is about 50 feet long.

I'm a bit confused on your extrapolation about the chasm, the bridge, etc. The Balrog stands at the foot of a bridge. The bridge reaches 50 feet to the far side of the chasm. Given that its wings spread "from wall to wall" perpendicular to the bridge, how can we infer anything about its wingspan from this information?
