Ed was keenly aware that the whole 'flying isn't working because long-standing charms are affected' answer from the Minister totally proved his point that it was worth knowing.  Also, he thought, if they definitively knew flight was dangerous then maybe the public should be notified - just because something was banned didn't mean people wouldn't try it in desperation.  But, while he didn't especially mind the negative vibes from the other department Heads, he definitely didn't like earning the Minister's ire.  His mild but quelling tone was enough to keep Ed from pointing out he'd been right.

He leaned comfortably back in his chair, listening as various people chimed in - animals, werewolves, atmosphere charms, attacks.  All things he was no expert in.  He even resisted a smirk when Mr. Skeeter got roped into spear-heading something.  Further proof that while the execution had not been flawless the result was exactly as he'd hoped - his part was taken care of early and they'd moved on.  

"I am sure there are a number of able and willing people in Games and Sports not directly under Mr. Skeeter's command who can be rallied if more hands are needed." he offered.  He may not know the cause - and why would he? they had entire departments for that - his department could still be of use.
