[goes one to descibe one method of doing this]

Last I heard, several airports had an arrangment of (Jet engines?) along the
side of one runnway, and a pilot could request (if he thought ground 
visibility was insufficent) that these be turned on to clear the fog.
	This is something I remember from reading some magazine several
years ago.  Does anybody know what airports this is still working at? (or
was it just my imagination and this never got past the proposal stage.)
