glide path

[Benjamin Zimmer]

Today's Word Routes column is about the term "glide path", which Pres.-Elect
Obama has used metaphorically twice in the space of a week (re the economy
and the Iraq War):

It's been used figuratively (mostly in economic usage) at least since 1973,
but this extension is not yet in OED or other dictionaries I checked.
