If balrogs had wings how could they fall?

[Varda]

I hope this doesnt bring up a sore subject, since I know this is hotly debated, but..... my roommate just brought up a point that sounded interesting. She just finished reading LotR for the first time. She remarked that if a balrog did have wings it could not fall. Yet perhaps it could still fall with wings if the wings were not useful for flying but were kind of like the wings of a penguin, which are used just for balance (i guess)..... if anyone is annoyed by me bringing this up, though, feel free to close this thread
