Not entirely certain if her power of flight is limited by her cape, seeing as how she was flying just fine back when she was in Africa and pretty much flew around in the nude.  I can't remember exactly, but she may even have been flying around sans cape way back when they fought Sauron (UXM #115).  

Storm may have greater finesse over her ability to fly.  We're seeing proof of that right here as she floats about in her placeholder attire.

This may be an argument better suited for Banshee.   Different writer/artists grant different levels of leeway  ---   because when he attacked *Weapon Alpha*  way back in UXM #109, he didn't require any "gliders".   Same as when he was containing Moses Magnum's attack on Japan;  he appeared to be in hover-mode, so the gliders seemed to be more an extension of couture over necessity.

It sometimes puzzles me what comic book readers will and won't accept.

Certainly if you aren't bothered by the first, then the second isn't an issue.

Sorry @JB.  As always, you beat me to the click.

I love Storm's modified look and look forward to seeing how it evolves either way. Her original is a classic, but this one underlines how regally she carries herself no matter how she's dressed.

In a world where people can walk through walls, shoot lasers out of their eyes, or burst into flame at will ---  it does seem a little zany for folks to quibble over the "realism" of flight capes   >:^D

*guilty!*

Maybe Edna Mode was onto something.
